Dynamic Quality Identification and Design of μ Synthesis Control for PMSLS
For the characteristic of high precision micro-feed and super low speed permanent magnet linear synchronous servo system(PMSLS)suffering from the effect of load disturbances and parameter variations, the H∞ controller design methodology is combined with D-K iteration in μ synthesis to design a μ synthesis controller. This μ synthesis controller is better in robustness against load disturbances and parameter uncertainties. In order to compensate friction disturbance and increase robustness, the dynamic quality is identified on-line based on model reference adaptive control. According to Simulation result, the proposed μ synthesis controller meets the requirement of the robustness and rapidity for PMSLS, and the system has high steady state precision.
