Abstract

Design method of loop transfer function on expected phase for robust gain system is proposed. Bode ideal loop function (BILF) can guarantee the strongly gain robust stability for closed loop system, while the desired fractional order (1~2) BILF has to be approximated with high integer order function to be implement. Low integer order controller, the conventional proportional integral and derivative (PID) controller, can compensate process function to be BILF on phase in mid-band frequency. So, the PID parameters can be obtained with phase fitting in appropriate frequency range. Examples are used to illustrate the proposed approach. Simulations show that this proposed method is effective for multiple lag and/or time delay processes.
