Reinforcement learning is a powerful method for solving sequential decision making problems. But it is difficult to apply to practical problems such as multi-agent systems with continuous state space problems. In this paper we present a cooperative strategy learning method to solve the problem. It combines WoLF-PHC algorithms with function approximation of RL techniques. By this method an agent could learn cooperative behavior in the multi-agent environment with continuous state space. Using a subtask of RoboCup soccer,Keepaway, we demonstrate the effective of this learning method and the experiment results show that the algorithm converges.

This paper presents a method of fuzzy gain scheduling for a PID controller applied to mean arterial pressure (MAP) regulation during general anesthesia by sodium nitroprusside (SNP) infusion. A supervising algorithm is used for online updating the fuzzy gain scheduler of the PID controller to act stronger against the body reaction. A new model based on Slate's model and Furutani's ideas was developed for testing the controller. Simulation and clinical results in deep hypotensive controls at 40mmHg on pigs indicate the safety and stability of designed controller. Copyright © 2005 IFAC.

Novel iris recognition method

Guangdian Gongcheng/Opto-Electronic engineering 2005年第5期32卷 89-92页

作者： Zhang, Peng-Fei Li, De-Sheng Wang, Qi Department of Automation Measurement and Control Harbin Institute of Technology Harbin 150001 China College of Mechanical Engineering and Applied Electronic Technol. Beijing University of Technology Beijing 100022 China

A novel iris recognition method based on multi-texture feature fusion is presented in the paper. The extraction of the texture features with different resolutions in different directions are carried out by performing Gabor wavelet transform for iris image and the extracted features are used as global features of iris. The local features of iris are extracted by applying gray scale level Co-Occurrence Matrix (COM) to the filtered sub-window image. The global features and local features will be recognized and sorted by weighting Euclidean distance and the minimum distance, respectively. A sorting method with Fuzzy Inference System (FIS) feature fusion is designed to improve the robustness of iris recognition. Experimental results show that the method is effective and feasible with recognition ratio up to 98.5%, False Acceptance Rates (FAR) lower than 0.1% while False Rejection Rates (FRR) keeping 1.4%.

2004 IFAC Workshop on Programmable Devices and Systems, PDS 2004

作者： Martinák, Lukáš Oujezdský, Aleš Slíva, Aleš Department of Measurement and Control Faculty of Electrical Engineering and Computer Science 17. listopadu 15 Ostrava-Poruba708 33 Czech Republic Institute of Transportation Faculty of Mechanical Engineering VŠB-Technical University of Ostrava 17. listopadu 15 Ostrava-Poruba708 33 Czech Republic

The paper deals with a bulk solid pressure observation inside a silo using new developed 3Dimensional (Triaxial) Indicator. New design and conception of the 3D indicator have been developed exclusively for detecting of real stresses/pressures inside vessels, bunkers and silos. The unique design of the 3D indicator in cooperation with appropriate used software, and with a silo model is able to assure a clear image to pressure/stress identifications in particulate solid. Moreover, the third dimension is unique and enriches the area of the pressure knowledge. The measurement process incl. the procedure of processing values using the created interactive software environment has been explained in the poster intimately and investigated in a real silo loaded by a poured bulk solid. Real results and outputs of the investigation have been presented and discovered in the paper. © 2004 IFAC.
