- Abstract
In order to solve the problem that the parameters of full — format dynamic linearization model — free adaptive control algorithm are difficult to tune, a FFDL — MFAC algorithm parameter tuning method based on incremental PD con-trol algorithm is presented. Firstly, by comparing the similarity between incremental PD control algorithm and FFDL —MFAC algorithm, the relationship between parameters Kp and ICI) of PD control algorithm and parameters of FFDL —MFAC algorithm is obtained, which simplifies the parameter tuning process of FFDL — MFAC algorithm. Then, taking complex single degree of freedom magnetic levitation system as a controlled object, the effectiveness of FFDL — MFAC parameters tuned by PD algorithm is verified. The simulation results show that the parameters of FFDL — MFAC control-ler tuned by PD algorithm can make the controlled object stably levitate, and the stable state can be quickly restored after adding disturbance. The experimental results show that the FFDL — MFAC controller tuned by PD algorithm has faster response speed and stronger robustness than PD controller.
