摘要
Abstract
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 modulation to achieve ideal parameter identification without needing specific excitation (such as M sequence), which can preserve the system operation from the interference of pseudo-random sequence. And this method has the features of simple principle, small amount of calculation, high real-time performance, and wide application.关键词
