摘　　要：为了提高伺服系统的动态响应特性,可对负载转矩进行前馈补偿,对电机机械参数进行辨识。介绍一种基于状态观测器的扰动负载转矩观测法,以及依据自适应法对转动惯量进行辨识的方法。仿真和实验验证了该方法的正确性和可行性。In order to achieve high dynamic response characters of servo systems, it is necessary to complete feedfor- ward compensation with load torque and to identify the mechanical parameters of the motor. A technique for the disturbance load torque estimation based on states observer was introduced, and the inertia and friction identification based on adaptive identification was introduced. Both simulation and experiment demonstrate the feasibility and effectiveness of the proposed method.
