The increasing demand for cloud computing services to more flexibly use computing resources has led to a severe problem of excessive energy consumption in data centers. In recent research, the energy consumption of computing and cooling equipment has attracted much attention. To reduce the energy consumption in data centers, the energy efficiency of the cooling equipment needs to be considered. This study theoretically modeled the relations between the server's internal heat sources and exhaust temperatures. First, we proposed a model that expands the previous study to describe the temperature change delay and to apply it to multiple internal heat sources. Then, we experimentally evaluated the prediction accuracy of the proposed model using a real server and conducted a simulation to confirm the efficiency of this prediction model for load balancing. The simulation results showed that the proposed method reduced the average maximum server temperature by 0.27 °C compared to the conventional method, which theoretically leads to energy savings of 260 kW per day and 95 MW per year in typical data centers.

Maglev planar motor is a novel planar motion device in precision/ultra-precision industry, while its precision motion control still needs further study. In this paper, a model prediction based online feedforward compensation (MP-OFC) control strategy is proposed for maglev planar motor to achieve excellent tracking performance. A system prediction model considering external disturbances and unmodeled factors is established to accurately predict tracking errors at future sampling moments online. Consequently, an iterative calculation scheme is designed to generate the feedforward compensation term as reference trajectory modification during real-time motion. Comparative simulation experiments consistently validate that the proposed MP-OFC strategy outperforms other controllers much, and the MP-OFC achieves excellent tracking accuracy for various trajectories even under complicated external disturbances.

Efficient oxygen excess ratio (OER) control has a vital impact on prolonging the lifetime and excavating the potential for net power improvement of proton exchange membrane fuel cell (PEMFC). However, unknown uncertainties such as dynamic load scenarios, system nonlinearity, and noise make OER control challenging. In this article, the active disturbance rejection controller (ADRC) is applied to control the ORE at its set value by manipulating the compressor voltage. It regards the uncertainties of nonlinearity and disturbance as the “lumped disturbance”, and then the extended state observer (ESO) is designed to estimate and compensate it in real-time. Next, according to the structure of ADRC, the final control law is derived. Finally, a high-fidelity model is used to verify the controller, and the simulation results demonstrate the effectiveness and superiority of the designed controller compared to the baseline controller.

This paper develops a haptic feedback control stick for remote control of a two parallel wheeled rover. The authors apply a bilateral controller for this remote operating-operated system in which their structures are different. Thus, the developed haptic feedback control stick plays a role as not only an input device to give the velocity information to the system but also an output device by which the operator feels an estimated external force applied to the wheel of the rover. The haptic feedback control stick is strongly expected the operator can control the operated rover more intuitively and more safely. In this paper, the authors experimented by combining a linear-slide-type control stick and a single wheel computer simulator of the rover. However, the operator felt a force except the estimated force to the rover's wheel, in conditions that a time delay occurred because of a large dynamical difference between the control stick and the rover. Therefore, two types of experiments were compared, i.e., one used only the bilateral control and the other used switching the bilateral control and the force control according to a value of the time delay. These experimental results were discussed and evaluated as focusing on a situation when a time delay occurred.

Intelligent control has received a significant amount of attention in recent years owing to its use in autonomous driving technology and other applications(1)-(3). Intelligent control is a control theory that uses machine learning algorithms to build control systems. In this study, we develop an intelligent control theory based on deep reinforcement learning. We proposed a reference signal self-organizing control system based on a deep deterministic policy gradient (DDPG). This proposed system is an extension of an existing control system using DDPG. We verify the effectiveness of the proposed system through swing-up and stabilizing control simulations using an inverted pendulum with an inertia rotor. We confirmed that the pendulum was inverted by the swing-up control at approximately 1.2 s and the pendulum was stabilized for approximately 8.8 s. Therefore, we confirmed the effectiveness of the proposed reference signal self-organizing control system.

Weathering steels possess excellent corrosion resistance due to the precise protective rust layer formed on the surface, which suppresses further corrosion. Due to its superior weatherability, weathering steels are used for bridges, external walls of buildings, and outer surfaces of railroad vehicles. However, weatherability cannot fully inhibit corrosion due mainly to a high salt level in the atmosphere. Therefore, the rust condition of weathering steels must be regularly inspected and evaluated. Currently, the rust conditions of weathering steels are assessed by visual inspections. The drawbacks of this method are that it requires inspectors with expertise and lacks accuracy and repeatability as it is a subjective assessment. We have developed a system capable of quantitatively assessing rust conditions of steels. Previously we proposed a method to evaluate rust conditions of weathering steels by capturing images of rust with multiple lighting devices and cameras, and subsequently processing the captured images. In that study, we fabricated an image capturing device and confirmed that rust conditions of weathering steels could be evaluated accurately. Herein we report a modified image capturing device, which is smaller, lighter, and can be operated remotely. Our modified image capturing device can travel upwards, downwards, and horizontally. Additionally, it can be operated by a remote control from 80-m away.

The purpose of this study is to maximize the remote participation experience of disabled and elderly people who have mobility problems. We reviewed the prior art on visual interfaces from two aspects and proposed a stereo matching interface to improve their combined performance. The first aspect is hedonic quality as it relates to reality of going-out experience and usability. The second aspect is that of utility. Our visual interface is a human-assisted sensing system that enables the user to move the remote-controlled robot as intended by allowing the user to predictably recognize remote depth information. Depth recognition of an arbitrary point on the display is possible just using a planar image from the robotic perspective. In this study, performances of specific tasks resulting from use of the interface were experimentally validated. The results of the stereo matching task on the display between the target feature point and its depth index as summarized by edging showed that the slower the relative approach velocity was, the easier the stereo matching task was. However, various designs created to achieve the relative approach velocity conflicted with design constraints meant to improve usability or hedonic quality.

This paper focuses at charge estimators of piezoelectric actuators with a sensing capacitor. They have been claimed in the literature to be outperformed by their newly emerged competitors, charge estimators with a sensing resistor, widely known as digital charge estimators. This paper proposes a digital implementation of capacitor-based estimators and compares them with resistor-based ones both analytically and experimentally. Although, the sensing capacitors are normally bulkier than the sensing resistors used in newer resistor-based estimators; a resistor-based estimator needs to have a variable resistance to deal with different excitation frequencies satisfactorily; this is a major drawback which does not exist in capacitor-based estimators. Both capacitor-based and resistor-based estimators, if designed appropriately, are quite comparable in terms of voltage drop and range of measurable charge. This research concludes that capacitor-based estimators, with right design and implementation, can be still of wide use in nanopositioning.

Quantifying walking stability is needed in order to evaluate the various walking assist methods. It can also allow the planning of individualized interventions for elderly people or patients with disorders. The Gait Sensitivity Norm (GSN) is a new measure of the walking stability developed for passive dynamic walkers and has been reported to show a strong correlation with the fall risk. The GSN is a method based on the idea of the $H_{2}$ norm, which allows us to know the dynamic response of the system of walkers by measuring the impulse response. The reliability of the GSN quantification has been confirmed in passive dynamic walkers and neuromusculoskeletal walking models. However, it has not yet been applied to humans. In this paper, we proposed a method to apply the GSN to the analysis of human walking. To apply the GSN to a human gait, wearable sensors were used to analyze human walking. The validity of quantifying gait stability with the GSN is assessed in the experiments comparing abnormal walker (with some weight or blindfold) and normal walkers. The result is consistent with the intuitive idea that blind walking is more unstable than normal walking.

A mechatronic product is subject to many influencing factors, which have to be considered in the course of development. An early evaluation of these factors is a difficult task, requiring the consideration of numerous interactions. In this paper, the development of a simulation model for the evaluation of the sensitivity of a mechatronic system is described, using the example of a light guide. By applying Design of Experiments (DOE), the influence of individual design parameters on the overall system is determined and the robustness estimated. The investigation aims to compare the influence of mechanical and electronic parameters and their effect on the sensitivity of a mechatronic product. The results from the virtual model are then interpreted for further development of the light guide.
