The design and simulation of controllers for high order system

In this paper, three controllers, which are the integer order PID(IOPID) controller, the fuzzy PID(FPID) controller and the fractional order PID(FOPID) controller for a class of high order systems, are designed. From the simulation, the three controllers designed work efficiently. Moreover, it is interesting to observe that the dynamic characteristic of the designed system based on the FOPID controller outperforms the other controllers.
