最小二乘法测量直流伺服电机动态时间常数

Dynamic Parameter Estimation of D C Servo Motor by Least Square Method

提出用最小二乘曲线拟合法测取直流伺服电机动态参数．在电枢两端施加阶跃电压，测量．电枢电流的暂态响应，通过最小二乘曲线拟合，可以求取直流伺服电机动态时间常数．

A dynamic parameter estimation of D C servo motor by the least square estimation is presented in this paper. A step voltage is imposed on the armature head of D C servo motor,transient responses to armature currents are recorded, and its dynamic parameter can be estimated by the least square method.
