A Method of Parameter Identification Based on Least Squares for Torpedo Propulsion Motor
鱼雷推进电机在运行过程中,由环境温度改变引起的电机参数(包括电阻、电感、风阻系数等)变化会对控制性能造成不确定的影响.本文以电机的微分方程为基础,直接构造基于最小二乘法的目标函数,从而得到电机参数.该方法原理简单、运算量小、实时性高、适用范围广,特别是无需特定的激励源,只需采用脉宽调制激励源就可以得到理想的辨识效果,避免了伪随机序列激励对系统运行造成的影响.
The torpedo propulsion motor's parameters, such as resistor, inductor, and viscous coefficient, vary with the ambient temperature, which usually leads to structure change and uncertain influence on the control system. In this paper, an objective function based on least squares is established by making use of the differential equations of propulsion motor to obtain the motor's parameters. This method only adopts the excitation source of pulse width modu…查看全部>>
