Design and simulation of a kind of fuzzy self-adapting PID controller

This paper uses the theories of fuzzy control and self?adapting control to adjust the parameters of the PID controller by itself along with the variety of the mathematics model of the object.It describes the feasible design scheme and makes simulation experiment of the controller with the use of C language.The test demonstrates that this fuzzy self?adapting PID controller is much better than the conventional PID controller in the respects the dynamic?state and steady?state characteristics such as the stability,response speed and overshoot and the adaptability of parameter?time?varying system.
