For dual linear motor cooperative control system, there is only one controlled input signal can be used. Each linear motor of the control system is independent. Therefore, the position loop of control system is easier to be disturbed. This paper presents a 2DOF PID controller to position loop for dual linear motor cooperative control system so that the two groups of parameters can be adjusted independently. The simulation result shows that the system has a strong robust and also has a good anti-disturbance performance and setting value tracking ability which has a good application prospects. The dynamic responsibility of dual linear motor cooperative control system based on two degrees of freedom (2DOF) PID controller is faster than traditional PID controller.

Oil debris monitoring (ODM) is a significant technique for contaminate particle detection in real time for hydraulic systems. Current radial magnetic oil debris detector only provide the acceptable debris detection accuracy under the single particle. When two or more debris particles are generated in the oil and they pass through the debris sensor, the aliasing effects occur in detection signal and the error will be introduced. This paper presents a new debris monitoring structure based on two or more debris sensors. Through cross signal processing, this paper separates the mixed signal of oil debris monitoring and gives the accurate contamination particle detection. Simulation results indicate that the proposed mixed signal separation method is effective to identify and separate debris aliasing signal.

Object detection is a hot spot of the research in computer vision since many applications require the determination of the object location. There are many object detection methods based on feature matching methods. In this paper, we locate object on robot operation system. The SIFT keypoints of the template and test images are extracted at first. Then, the matching method is proposed to find the template image which is closest to the test image. The matching method is applied on the closest template image and the test images. Finally, we use affine transformation to get the rectangle represents the location of the object. Our system is a robot arm based on robot operation system(ROS). This robot arm consists of six degrees of freedom. In the experiment, we represent a result of object result using the images obtained form the camera installed on the robot arm. Our system is helpful to locate object on robot operation system.

In this paper, considering the decode-and-forward (DF) relay scheme, we study the optimal design of power allocation for orthogonal frequency division multiplexing (OFDM) secure communication, where the relay carries out wireless information and power transfer (WIPT) by time switching(TS) scheme. Our objective is to maximize the achievable secrecy rate subject to the power constraint of the source and the energy harvesting (EH) relay. However, the problems are non-convex. By exploiting their special structure, we equivalently transform the non-convex optimization problem into a quasi-convex problem and solve it by a simple algorithm using bisection. At each step of the algorithm, we will solve a convex feasibility problem by the Karush-Kuhn-Tucker (KKT) conditions and obtain the closed-form solution. At the end, simulation results verify that the proposed optimal solution outperforms that for conventional equal power solutions.

At present, the capacity of most residential areas cannot meet the need of large-scale EVs (Electric Vehicles) charging. A strategy of coordinated charging for private EVs in residential area is proposed. Based on daily trip habit of EV and base loads of residential area, the method seeks for the period of the lowest total loads and arranges EVs for discontinuous coordinated charging in the valley period that makes sure the total loads are flat as soon as possible. The daily trip rule of EV user is simulated by Monte Carlo method, and the load condition of distribution transformer under three charging modes, namely the uncoordinated charging, the continuous coordinated charging and the discontinuous coordinated charging, are simulated and analyzed. Research results show that the discontinuous coordinated charging can reduce peak-valley ratio significantly and cannot cause new peak load, thus it is suitable for practical application.

New fault diagnosis and active fault tolerant control (FTC) algorithms are proposed for a class of nonlinear singular stochastic distribution control (SDC) systems in this paper. Different from general SDC systems, in singular SDC systems, the relationship between the weights and the control input is expressed by a singular state space model, which increases the difficulty in the design of fault diagnosis and fault tolerant control. A non-singular state transformation is made to transform the singular dynamic system into a differential-algebraic system. An adaptive nonlinear observer is designed to estimate the size of the fault occurring in the system. Furthermore, the linear matrix inequality (LMI) approach is applied to establish sufficient conditions for the existence of the observer. Based on the estimated fault information, the active fault tolerant controller can be designed to make the post-fault probability density function (PDF) still track the given distribution. At last, an illustrated example is given to demonstrate the effectiveness of the proposed algorithm, and satisfactory results have been obtained.

Energy efficiency and power crises are the critical issues that the globe is facing nowadays. Generation diversification, Demand Response, renewable energy accommodation, and reduction of Carbon dioxide emission are some of the issues that cannot be covered within the limitation of the current grid system. Smart Grid has revolutionized the generation, Distribution, and Consumption of electricity by integrating intelligent control, sensing and communication in daily operation of the electric grid. The goal of the Smart Grid is to be environmentally sustainable, for the deployment of this trending technology is a must. This paper addresses the issues that would be faced in the implementation of the smart Grid technology, policy consideration to maximize the benefit of smart grid and enhance the benefit over cost ratio. It explains the three sectors where the smart grid applications can be seen with challenges in bottom-up design, and overview of Smart grid for utilities. A top-down scheme is presented which can help in eliminating the challenges and barriers in the smart grid implementation. Finally cost vs. benefit analysis is made to prove the effectiveness of this trending technology in the power sector.
