Abstract
This paper deals with the self-adaptive fuzzy PID controller. The control rule is designed to realize the parameter's self-adaption of PID controller by using fuzzy logic control. The control system has a higher precision and a response speed with the self-adaptive time being reduced from 2 second to 0.33 second. The performance of the endpoint is improved and it has better robot with no exceeding the expected area of fuzzy control. This self-adaptive fuzzy PID control system is an organic combination of Fuzzy Logic Toolbox and SIMULINK,its computer simulation is convenient,and it will widen the application of MATLAB.
