摘要：
In this paper, a novel fractional order proportional-derivative (FO- PD mu-1) controller design algorithm is proposed for a class of linear systems. The proposed control algorithm is developed using frequency domain approach. As the controller has three parameters to tune, three frequency domain specifications such as phase margin (phi(m)), gain crossover frequency (omega(gc)) and velocity error constant (K-v) are chosen as desired specifications. Modified Ostaloup recursive approximation (M-ORA) method and MATLAB curve fitting tool are used to realize the (K-v) specification. The proposed controller is implemented in simulation. The results show that the proposed FO - PD mu-1) controller provides better results than the existing controllers.
