| Abstract: | Based on model matching, the configuration of a two - degree - freedom servo controller for permanent magnet linear servo system is modified. The tracking performance of the system at objective parameter perturbation is improved by using inner part model. The desensitization performance at system parameter perturbation is elevated by using feed-forward part model. Matlab simulation results verify the validity of the system design. Overall robustness of the servo system is improved obviously. |
