Fractional Order (Pid Mu)-D-Lambda Control For Maglev Guiding System

To effectively suppress the external disturbances and parameter perturbation problem of the maglev guiding system, and improve speed and robustness, the electromagnetic guiding system is exactly linearized using state feedback method, Fractional calculus theory is introduced, the order of integer order PID control was extended to the field of fractional, then fractional order (PID mu)-D-lambda Controller was presented, Due to the extra two adjustable parameters compared with traditional PD controller, fractional order (PID mu)-D-lambda controllers were expected to show better control performance. The results of the computer simulation show that the proposed controller suppresses the external disturbances and parameter perturbation of the system effectively; the system response speed was increased; at the same time, it had flexible structure and stronger robustness.
