Due to the increase in worldwide energy demand, wind energy technology has been developed rapidly over the past years. With a fast growing of wind power installed capacity, an efficient monitoring system for wind energy conversion system (WEC) is required to ensure operational reliability, high availability of energy production and at the same time reduce operating and maintenance (O&M) costs. The state of the art methodologies for WEC condition monitoring are signal analysis, observer-based approach, neural networks, etc. In this paper, an effective and easy adaptable multivariate data-driven method for wind turbine monitoring and fault diagnosis is introduced, which consists of three parts: 1) off-line training process 2) on-line monitoring phase 3) on-line diagnosis phase. The performance of this method is validated for detection of sensor abnormalities that have occurred in real wind turbines.

In this paper, the tracking control for air-breathing hypersonic vehicles in cruising flight is studied, where the super-twisting algorithm is utilized to design a continuous controller. The nonlinear transformation is used to clarify a control-oriented model for hypersonic vehicles. A second order sliding mode controller based on the super-twisting algorithm is designed for the tracking of velocity and altitude, and Lyapunov approach is involved to analyze the stability of closed loop system, which also demonstrates that sliding mode surfaces converge in a finite time. The super-twisting sliding mode control has the ability to reduce chattering and also is robust against varying parameters. Simulations are shown to validate that the proposed method has reduced chattering efficiently and the robustness has been also guaranteed.

In this paper, a class of nonlinear systems with parametric uncertainties in the control inputs are taken into consideration and several control design approaches are investigated and compared by simulation studies. As for nonlinearity, one popular method is gain-scheduling, of which the main idea is to linearize the system at many operation points and then adopt linear control design. However, it could not achieve good performance in the presence of uncertainties. Augmenting the gain-scheduling controller with adaptive control law may improve the closed-loop dynamics, but another disadvantage is the large quantities of data processing in advance resulting from linearization which would be impossibly addressed once we take the gain-scheduling as control strategy. Therefore, nonlinear control technique of less dependence on the mathematical model is our best choice. ADRC (active disturbance rejection control) benefits from its ESO (extended state observer) to cope with the disturbance and uncertainties. Moreover, the nonlinear feedback control based on ESO upgrades the performance of the closed-loop system. Simulations are conducted to validate the effectiveness of ADRC, and comparison is carried out to figure out advantages and disadvantages for each control law.

Many important dynamic systems operate in uncertain environments, and in many cases even small levels of noise can severely compromise their performance and stability. In this work, we propose a robust design approach to improve the performance of such systems. Our approach first specifies a set of linear constraints describing dynamic performance requirements based on pole position concepts. Next, a robust linear programming model is solved to yield a parameter design which achieves the performance requirements as well as possible under uncertainty. The effectiveness of our proposed approach is supported with computational studies on a Voice Coil Motor (VCM) in a commercial Hard Disk Drive (HDD).

A noise immunity automatic test method for analog acquisition module of control system based on virtual instrument is proposed. The traditional method is too complicated and inefficient. This paper designs a set of efficient common and series mode noise immunity automatic test system based on virtual instrument. Through the programmable function of virtual instrument we develop test processes such as signal source input, disturbance exerting, data acquisition, data recording and dynamic analysis, and test report can be generated automatically. The experimental results show that the common and series mode noise immunity automatic test system based on virtual instrument can work continuously for a long time, and can do multi-channel parallel test, which significantly improves the test efficiency.

In this paper, we consider the distributed protection of a target region by a group of agents with switching interconnection topologies. We propose a distributed controller to achieve the distributed set projection with the same distance and different rotation angles specified by a complex-value adjacency matrix. With mild connectivity assumptions, we prove that all agents can protect/surround a target described by a convex set in a plane.

Indoor positioning based on wireless signal strength is inaccurate due to unpredictable wireless channels at complex environments. In this paper, we propose another approach for guiding a self-propelled car. We implement a wireless navigation system which consists of a self-propelled car, several Zigbee reference nodes, and a suit of navigation programs. The reference nodes, which are placed on the desired path, send beacon packets to indicate the direction for the self-propelled car. Only one reference node is active at a time. When the self-propelled car arrives at the current active node, the guiding duty is switched to the next reference node. By this way, the self-propelled car can visit these reference nodes one by one to the destination. The self-propelled car, equipped with a rotational directional antenna, continues rotating its antenna to find the direction of the active reference node according to the signal strength of receiving packets. The wireless navigation system is proved effective by prototyping.

The EMS (Electromagnet Suspension) maglev system uses controlled electromagnetic forces to achieve suspension, and self-excited vibration may occur due to the flexibility of the track. The harmonic balance method is applied in this article to investigate the amplitude of the self-excited vibration, and it is found that the amplitude of the vibration depends on the voltage of the power supplier. Based on this conclusion, a vibration amplitude control method, which controls the amplitude of the vibration by adjusting the voltage of the power supplier, is proposed to attenuate the vibration. A P1 controller is designed to control the amplitude of the vibration at a given level. The effectiveness of this method is validated by a simulation, which shows a good prospect for its application to real maglev systems.

Endothelial glycocalyx has been recognized as a mechanotransducer of shear stress to the intracellular cytoskeleton. The elastic property of glycocalyx plays an important role in the red cell movement in the capillary vessels, but the measurement of rigidity is a great challenge. In this paper, we hypothesize that the support force of glycocalyx is caused by the interaction of electrostatic force of the protein in the glycocalyx. This effort is studied by introducing a beads-stick model with negatively charged core protein in each glycocalyx strand linked by a rigid stick. The deformation and recovery caused by the shear stress has been investigated.

In this paper, a key performance indicator (KPI) related multiplicative fault diagnosis scheme is proposed for static industrial processes. This scheme is developed for an alternative algorithm to the standard partial least squares (PLS) based process monitoring, where no design parameter like “latent variable number” is involved. Based on both normal and faulty data sets, the multiplicative fault information is firstly estimated. With this knowledge, the most critical low-level control loop/component is further identified. Different from the existing data-driven additive fault diagnosis approaches, this scheme aims to handle the second order statistics, which is of fatal importance for KPI-related fault diagnosis. Finally, an academic example is investigated to illustrate the functionality of this scheme.
