This paper discusses tracking control problem with a discrete-time multi-agent system with active leader and quantized communication constraints. For the active leader in a general linear form, we give a distributed design for each discrete-time agent in the leader tracking control problem and analyze the tracking convergence with the help of Riccati equation and common Lyapunov function when the communication channel is perfect. Then a stochastic quantization strategy is applied to model the information transmission in the agent coordination and the corresponding solution is also given, even if the interconnection topology is switching.
Aiming at the cooperation of Agent in multi-Agent system, the game theory was introduced to the cooperation of Agent, and the multi-Agent cooperation mechanism based on game theory was established. The common multi-Ag...

The feature extraction is key step to fault diagnosis in nonlinear circuit. An improved particle swarm optimization (PSO)algorithm are presented to competent for the identification and feature extraction problem in nonlinear circuit here. Firstly, the output response from the circuit under diagnosis will be collected and processing, some order frequency-domain kernel function under can be extracted as circuit feature for fault diagnosis. Secondly, the single feature or whole feature group of circuit can be seek by particle swarm optimization solution, the improved article swarm optimization algorithm apply to the searching for optimization solution of system identification based on frequency domain kernel of the nonlinear circuit. At last, the circuit diagnosis result will be give. The results shown: the algorithm is competent for the system identification optimization and pattern classification problem well, the diagnostic efficiency is high.

The mathematical model of brushless dc motor system (BLDCMS) is proposed. First, the BLDCMS is researched including the motor, inverter and controller. The key mathematical model of inverter drive circuit is established by introducing an impulse function and Fourier transform. This mathematical model converted current loop output voltage into actual PWM voltage that representative the inverter switching on or off. Therefore the BLDCMS model could be established easily according to the inverter model. Next, the simulation results and experiment results are presented respectively, confirming the validity of the proposed mathematical model. The simulation results show that this BLDCMS model is correct and meet the requirements.

Although abdominal operation is a kind of important clinical surgery, recovery of the post-operative is usually evaluated by the judgment of doctors. This traditional medical care mode may take much time of medical staffs and meanwhile increase the expense of patients. In this paper, a recovery evaluation system is established for the abdominal post-operative by using body sensor networks (BSN). The evaluation system can collect acceleration signals from five parts of human body and surface electro myographic (sEMG)signals from abdomen muscle group (AMG) during a user'sdaily activities. An experiment as a pilot study has been conducted to test the validity and feasibility of the system. The experimental results showed the evaluation system may effectively acquire the relationship between a user's daily activities and intensity of AMG. The study work in this paper may be used as a basis for further study on evaluating recovery level of the actual post-operative.

In order to search and rescue the victims in rubble effectively, a 3D model of the cavity is required. This paper presents a cavity detection method based on machine vision for disaster rescue robot. Laser ring projection technique is developed to lighten the profile of cross-section of the cavity and draw It line around the internal surface. A CMOS camera is used to capture the images which consist of essential profile information as well as various noises. The method of image acquiring and image preprocessing is also described. However, due to the inevitable influence of the harsh environment and lighting conditions, the profile in the acquired image might be partitioned into several segments. Thus, a method of detecting the curve segments based on vector argument is proposed. The 3D model of the cavity is reconstructed by using a series of complete and accurate cross-section profiles which are fitted by the improved cubic B-spline interpolation. Experimental results show that the proposed profile tracking algorithm is effective and adaptable.
