To weaken the influences of the position-dependent periodic disturbances and parameter uncertainties, the robust repetitive controller was designed, which associated structure singular value theory with the discrete-time repetitive control theory. The problem of robust repetitive control was transformed into one of H∞ optimal control using linear fractional transformation. The robust repetitive controller was achieved using D-K iteration procedure and made the servo system have stability, robustness and tracking performance.

为了削弱周期性扰动及参数变化不确定性的影响，将重复控制和结构奇异值理论相结合，利用线性分式变换(linear fractional transformation，LFT)将鲁棒重复控制问题转换成H∞最优控制问题，采用D-K迭代法设计鲁棒重复控制器(robust repetitive controller，RRC)，实现系统的稳定性和鲁棒性，提高系统的跟踪特性。

A decoupling control approach based on inverse system method had been applied for the permanent magnet synchronous motor, which was multi-variable, nonlinear and coupled system. PMSM was decoupled into second-order linear speed subsystem and first-order linear flux subsystem. The servo robust controller was used to design linear closed-loop controller for the pseudo-linear subsystems.
