摘　　要：针对负载的变化而引起的转动惯量的变化问题,提出了一种基于转动惯量辨识的交流伺服系统速度调节器参数自整定算法。该算法根据速度调节器的参数与系统转动惯量成一定的关系,采用基于扰动观测器(DOB)的转动惯量辨识算法在线辨识系统转动惯量,根据辨识的转动惯量值实时自整定速度调节器的参数,使系统具有良好的动、静态性能。仿真结果充分证明了该转动惯量辨识算法及控制器参数自整定算法是可行、有效的。To the problem that the variations of load changed the inertia,an algorithm of self-tuning of speed regulator for AC servo system based on inertia online identification was proposed.According to the inner relation between on the parameters of speed regulator and the system＇s inertia,the proposed algorithm real-time automatically adjusted the parameters of the speed regulator using the identified inertia which was online identified by disturber observer（DOB）.The system had well dynamic and static characteristic with the proposed algorithm and the simulation results clearly demonstrated the validity and feasibility of the proposed algorithm.
