Test task scheduling problem in the dynamic environment (DTTSP) is an important issue in automatic test system. In this paper, a dynamic multi-objective evolutionary algorithm based on decomposition (DMOEA/D) is proposed to improve the adaptability of the environment changes in test process. The mathematical model considering the arrival of dynamic tasks is proposed based on the Markov decision process. Three standard test functions and two DTTSP examples are used in experiment for illustrating the performance of the proposed algorithm. The results show that the proposed algorithm has good performance in convergence and diversity. Almost all the performance metrics of convergence and diversity obtain stable statistical results. The result of convergence ratio of an algorithm is not good as other metrics because of the slow convergence rate. The results also show that the solutions obtained by DMOEA/D have better Pareto front than the dynamic multi-objective particle swarm optimization algorithm (DMOPSO).

To measure the high rotation velocity of a motor, this paper proposes a scheme based on an infra-red led pair and integrated chip technology. By analyzing the infrared LED pair working principle, this paper designs a framework including a signal processing algorithm to measure the rotation velocity and display it in real-time. In details, the paper describes the technical specifications about how to use a SCM (Single Chip Microcomputer) and photoelectric sensor to design the hardware circuit and software programming for this system. The hardware circuit, mainly including photoelectric sensor module, pulse signal processing and display module, uses AT89C51 microcontroller as the core chip. With a specific algorithm, the pulse signal sent into the SCM will be processed and the motor rotation velocity will be displayed on a four seven-segment digital tube. Experimental results show that the rotation velocity measurement system is stable, reliable and has a great potential for a wide range of engineering applications.

This paper presents the design of a 6-bit, 25 Msps, reference voltage programmable delay-line Analog-to-Digital Converter (ADC), which is aimed to use in the digitally controlled DC-DC switching converters. A new differential bias circuit is used to improve the linearity of delay cells and also the ADC. The reference voltage can be adjusted from 1.8 V to 2.5 V with 0.2 V step, and the input voltage range is limited within ±200mV around the reference voltage. This ADC is implemented in 0.18um CMOS process and works at 3.3 V power supply. The simulation results for this ADC show that, the power dissipation is 450 uW, ENOB is 5.96-bit, DNL and INL is less than ±0.55 LSB and ±0.42 LSB, respectively. The designed ADC has the power-and die area-efficiency, it can be used as the built-in ADC of the digital controller in the digitally controlled DC-DC switching converters.

Sparse channel estimation has attracted much attention these years, especially in the area of under water acoustic communication. Compressed sensing methods are popular recently because of their efficiency and stability. In this paper, a stable and fast algorithm termed Selective Regularized Orthogonal Matching Pursuit (SROMP) is proposed based on Orthogonal Matching Pursuit (OMP). By numerical experiments, performance of this algorithm is shown in comparison to conventional LS (least square) algorithm, basic OMP and Stagewise OMP. Simulation results indicate that this methods can estimate sparse channel effectively and accurately outperforming LS and OMP.

In this paper, we propose a distributed optimal control algorithm for deferrable loads scheduling under the constraint of electricity supply in power systems, which can make the aggregate load approach the planning electricity supply as close as possible. The problem of deferrable loads scheduling is transformed into an optimal control problem firstly. Then we propose ODC-S algorithm to adapt the case that the constraint of electricity supply is considered. The objective function is designed according to the control problem to schedule deferrable loads, represented by electric vehicles, and we aim to minimize the variance of differences between electricity supply and aggregate load as well as to keep the fluctuations of the differences at a minimum level, which can ensure the effective utilization of power resources in electricity market, and can also maintain the stability of power systems. Finally, simulation examples are given to illustrate the effectiveness of the proposed algorithm.

In this paper, an effective distributed adaptive control method is proposed to solve the second-order average-consensus problem for multi-agent system with nonlinear dynamics. First of all, the distributed adaptive law is put forward in order to solve the problem that each agent can only use its neighboring agents information. Then, the basic idea of backstepping is used to solve the second-order dynamics. Since the neural network has the favorable approximation capability, the uncertain nonlinear dynamics in this paper is solved by it. By combining the aforementioned several methods, the designed controller for each agent can guarantee the average-consensus behavior could be obtained and all the signals here are bounded. Finally, the effectiveness and feasibility of the proposed approach is illustrated by the simulation examples.
