摘要
讨论了利用离散趋近律设计不确定离散时间系统的变结构控制问题,针对离散趋近律造成系统的抖振,设计了离散积分变结构控制(IVSC)策略,应用于永磁式同步电动机(PMSM)位置伺服系统。仿真结果表明,离散积分变结构控制策略可以明显改善系统的品质,增强系统的鲁棒性。
The design of discrete variable structure control (VSC) of uncertain discrete time systems using the reaching law is discussed. IVSC approach is presented to achieve accurate servo tracking to permanent-magnet synchronous motor control system in the presence of load disturbance and parameter variations. Compared with PI controller simulation results demonstrate that the IVSC approach can improve dynamic performances of system effectively and enhance the robustness.
