摘要: 为了使电枢控制式直流电机达到调速性能良好且便于工程实施的目的，通过对其数学建模并合理简化，得出转速与输入电压之间的传递函数，分别以理论推导和仿真试验得到传递函数中系数的求解方法，并根据所得系数设计出以伪微分反馈控制为算法的控制参数计算方法，据此采用AMEsim软件对直流电机速度响应能力、抗干扰性和鲁棒性能进行仿真分析，仿真结果表明采用伪微分反馈控制算法的直流电机调速系统具有响应快、抗干扰性能好、鲁棒性强等特点。

Abstract: In order to make the armature control DC motor achieve good speed adjusting performance and facilitate the implementation of the project, the reasonable simplified mathematical model of ar-mature control DC motor is built to show the transfer function between the speed and the input voltage. Solving method of transfer function coefficients is obtained by theoretical and experimental methods respectively. And according to the income coefficients, a pseudo derivative feedback control parameter computing method is designed. Finally, through the software simulation of the system performance analysis of speed response, anti-disturbance and robustness based on AMEsim, the results show that it has the characteristic of fast response, good anti-disturbance and robust performance using pseudo derivative feedback.
