Intelligent Optimization Theory And Isp Programming Techniques In The Design Of Intelligent Artificial Legs Controller

Intelligent artificial leg is an advanced intelligent mechatronic artificial leg, which is the fusion of intelligent control technique, microelectronic technique, computer control technique, mechanical design & manufacture, biomedical engineering and rehabilitation medicine engineering etc.. The amputate can walk with very natural gait after fixing it, which is very important to help them come back mainstream society to alleviate our society and their family's burden.Intelligent artificial leg is a complicated nonlinear control system. Fuzzy control strategy often is used to solve the control problem of nonlinear control object. The optimization of fuzzy controller and designing of peripheral circuit are two important aspects of fuzzy control system. In this paper, thus propose following methods:(1). Using genetic algorithm to optimize language operator of fuzzy set so as to optimize the tables of discrete membership function in fuzzy set The membership function optimized can objectively descript the characteristics of control object and effectively improve the performances of control system.(2). Using flexible polyhedron search algorithm to optimize fuzzy control rules.(3). Synthesizing respective characters of genetic algorithm and flexible polyhedron search algorithm to design a new hybrid genetic algorithm called flexible polyhedron genetic algorithm. The convergence speed and presicion of FPSA_HGA are higher than those of simple genetic algorithm.(4). Summarizing the synthetic applications of genetic algorithm, flexible polyhedron search algorithm and fuzzy set & fuzzy inference and enriching intelligent optimal theory.(5). Designing peripheral circuit of speed measurement for the control system by using the chip ispLSI 1016.
