摘要：

For the fractional order systems, a design method of fractional order proportional-integral-derivative (PID) controller based on Bode's ideal transfer function was proposed. Firstly, the relationships between the gain and the fractional calculus order of the Bode's ideal transfer function and the dynamic performance and robustness of the system were analyzed. Then, the Bode's ideal transfer function was used as the reference system, and the order of the controlled object was selected as the fractional calculus order of the controller. Moreover, according to the dynamic performance and robustness of the system, the gain K of the fractional order PID controller was tuned. So, the rules of the controller tuning were specified. The simulation results show that the proposed method is not only simple in design and convenient in parameter tuning, but also can provide a better dynamic performance, disturbance rejection property and robustness against the parameters perturbation of the system.
