为了实现某火箭炮交流伺服系统的高速、高精度位置控制，针对实际系统中存在的转动惯量和负载力矩变化大、冲击力矩强等各种不确定因素，提出了一种鲁棒最优控制方法。实验结果表明，该控制器鲁棒性强，而且具有较好的动态性能及稳态精度。

In order to realize high speed and high precision position control in an AC servo system,  in view of such kinds of uncertainties as moment of inertia and load moment changing widely,  and strong impact moment,  an optimal robust control tactics is put forward.  Experimental results show that this control tactics has strong robustness,  and has fairly good dynamic performances and steady-state precision.
