摘要
交流伺服系统具有良好的性能,但是难以精确地建模,同时,由于交流伺服系统和应用环境的复杂性,在系统参数变化和外界扰动的影响下,使系统的鲁棒性变差。采用H∞鲁棒控制混合灵敏度指标优化算法可以改善其鲁棒性,在进行实验仿真后,证明此算法可以有效地抑制参数变化和扰动带来的影响。
AC Servo System has perfect performance, but it is difficult to form mathematical model for it. A t the same time, due to complexity of AC Servo System and it's applying field, the Robustness goes bad under the inflection of changed parameter and the disturbance. The Robustness of AC Servo System can be improved while the algorithm of Hybrid Sensitiveness index optimization On H∞ Robust control be applied. It is tested that the algorithm can suppress the inflection of the changed parameter and the disturbance.
