The tuning principle of adaptive fuzzy fractional-order PID controller parameters

Using fuzzy method to adjust adaptive controller is fuzzy adaptive controlling, so-called adaptive controlling is that using modern control theory to recognize object’s characteristic parameters online and change their control strategies timely so that control system’s quality index could keep in the best range. Fractional order controller became a hot pot in recently years, when compared it with the common PID controller’s system we found that the former has shorter rise time, no overshoot or oscillations, and has stronger robustness. Especially, when the system has nonlinear and time-varying links, the adjusting effects will be excellent. Then the simulation of the fractional order controller combination with the adaptive controlling is carried out based on Matlab in this text.
