Due to the short fashion style life circle, much more different clothing designs show up. It is hard for consumers to find the suitable clothes effectively. To solve this problem, an automatic and reliable recommendation system is in great demand. In this paper, the clothing attributes recognition, gender recognition, and body height are considered to design the recommendation system. Based on the clothing style, gender and body height, the system can recommend the proper clothes with suitable size. On-line texture modeling is proposed to produce the variation of the clothing texture so that the recommendation system can give reasonable and diversified choices for the consumers. Besides, the data of consumers’ wearing style is also useful to make the better marketing strategy. According to the reasons above, the clothing recognition and recommendation system can create a win-win situation between the consumers and the fashion industry.

Nowadays, unmanned vehicles for navigation applications, such as factory unmanned vehicles and delivery dining systems, are becoming more and more extensive and gradually playing an indispensable role in our lives. Basically, navigation can be divided into three fields, the mapping, the localization and the path planning, in which the path planning is to use a pre-built map to plan a feasible path given the starting and the ending points. Hence, the path planning is the core part of the navigation operation, which is very important at the robot application level, such as the automatic driving and the driverless driving. For aircraft and space exploration, the path planning algorithms can be roughly divided into two types, the graph-based searching and the sampling-based searching. Among the two, the path planning based on random sampling provides with fast operation speed, high success rate on high-dimensional and complex problems, and disuse of extra considerations. The constraint of non-holonomic constraints, and the fast search for random trees are an algorithm based on random sampling. This paper mainly focuses on improving the path divergence in fixed iteration and on leading the direction from root to goal in fixed iteration condition. From the comparison of the experimental results, our approach is approximately 1.5 times better than the RRT on average path length.

In this paper, a security problem in control systems is studied. We consider a controller that transmits the control signal to an actuator. An attacker can compromise the controller in order to degrade the legitimate control signal. We investigate the prevention of attacks that lead to a premature aging of an actuator. We propose to limit the actuator’s output range in order to guarantee its normal aging’s behavior. To do so, we propose an invariant set-based approach for restraining the control input set. We provide mathematical tools, in term of Linear Matrix Inequalities (LMIs), for quantifying the invariant set of continuous-time deterministic Linear Time-Invariant (LTI) system with compact control input set. The proposed algorithm involves several convex optimization problems reduced to solving semidefinite programs (SDPs) for restraining the control input set for preventing aging attacks. A motor premature aging simulation example is presented to illustrate the performance of the proposed algorithm and shown the limits of the proposed algorithm.

Data-driven controller tuning methods directly design controllers using input/output data sets of a plant without using a mathematical model. This paper proposes a data-driven controller tuning method based on the H∞ control problem. The controller designed by the proposed method satisfies the H∞ criterion and stabilizes the closed-loop system. Furthermore, the proposed method derives a stable minimum phase controller. The controller is designed or tuned by iterative convex optimization. The effectiveness of the proposed design method is confirmed through comparison with the standard model-based H∞ control problem by simulations.

In this study, we aimed to use the motor-imagery electroencephalography (EEG) signal to construct a Brain Computer Interface (BCI) system. We developed an EEG-based real-time cursor control system on LabVIEW platform. EEG signals of left or right motor imagery on C3, and C4 channels were collected using OpenBCI amplifier system. The experimental protocol consisted of a training stage and a self-controlled stage with several runs in each stage. In the training stage, EEG signals were collected while subjects were asked to look at the moving cursor with a constant speed toward left/right, and pretended the cursor was controlled by their imagination. In the self-controlled stage, the movement of the cursor was controlled based on the concordance between the classification results and preset direction. Ten subjects were enrolled in this study. We found that the classification rate was associated with the consistency of the individual ERD/ERS frequency bands across different runs. If a subject presented a stable frequency band for the motor imaginary, the classification rate of the developed BCI system can reach a satisfactory performance with the highest classification rate of 93%. In conclusion, our results showed that the efficacy of our BCI system highly relied on the stability of the individual frequency pattern.

Smart devices surrounding us in daily life require frequent charging. To deal with the charging issue, wireless power transfer is a good option to provide energy due to its plenty of advantages, such as convenience, user-friendliness, and safety. A thorough wireless charging system consist of not only a transmitter and receiver, but also power generation, a controller, a charging station and a battery.Wireless charging enables charging easier for users. The communication between transmitters and receivers should be wireless as well. A communication system with various sensors forms an Internet of things (IoT) structure. It allows everyday objects with network connectivity to send and receive data so that they can talk to each other without human intervention. Moreover, it ensures that power is transferred in a precisely controlled way.This article uses a quasi-dynamic charging scenario to present the charging system, including an IoT structure and wireless charging, for an Arduino smart car. Our communication system is based on ESP 8266 NodeMCU which is a cost-efficient WiFi Microcontroller. The whole system is verified in experiment. The result shows that the system can provide good performance in a realistic situation, and a good basis for our next step–dynamic wireless charging.

In this paper, a Sliding Mode Control (SMC) was built to control a Brushless DC Motor (BLDC) with a Radial Basis Function Neural Network (RBFNN) for estimating the unknown and uncertain parameters. Otherwise, a disturbance observer was also designed to improve the robustness to external load with smaller control gain. And a logic rectifier for the equivalent of DC motor, it makes the commutation strategies easier for operating the BLDC in 4Q. To enhance the flexibility and integration in developing the algorithm for a motor control system, the real system was modeled in MATLAB Simulink and the speed control structure was built up so that it can be worked in both simulation and experiment. The system performance was verified in dynamic load condition by analyzing the transient specification, steady-state error for tracking response and by evaluating the speed reduction, recovery time for regulation response. The platform was implemented with the DSP F28379D LaunchPad.

Cloud technology uses the main function of IoT (Internet of Things) devices to quickly transfer huge amounts of data because data must be transmitted efficiently and efficiently among equipments. IoT enables smart devices to collect and share data without manual assistance. Compared to IoT, IIoT (Industrial IoT) technology is used for industrial purposes, but common industrial communication protocols such as Modbus TCP and Profinet only provide real-time data and cannot provide safe and reliable historical data. The OPC unified architecture (OPC UA) overcomes the above shortcomings and changes the entire industrial communication protocol and resolves the issue of object-oriented concepts. Other IoT protocols such as RTI DDS and MQTT do not emphasize the integration of industrial equipments. In this paper, we provide a solution enabling the smart robotic arm (Staubli) to convert its original communication protocol (SOAP/WSDL) into the role of an OPC UA server. This solution is successfully integrated in ERP/MES manufacturing production systems. The proposed method can help basic IoT robots be seamlessly embedded in ERP/MES manufacturing systems. We demonstrated how the OPC UA cloud computing platform worked. When a PCB color image was uploaded from the client, the OPC UA server processed it by the Gaussian blur and Canny filters and then returned the processed image to the client in a gray-scale image.

This paper proposes a “hybrid” model to quantify the aleatory and epistemic uncertainties of the transmission line’s failure while being enhanced by the dynamic thermal rating (DTR) system. The aleatory uncertainty propagates probabilistic failures, whereas the epistemic uncertainty propagates imprecision in the parameters of the failure model. The Arrhenius-Weibull model is used to characterize the end-of-life failures. The results in this paper shows that the proposed hybrid method relaxes the reliability evaluation criteria and as a result the produced reliability index is not fixed at a single value.
