Simulation and Research of Driving Motor Speed Control System for Electric Vehicle

摘要

In this paper, a mathematical modeling is set up based on the trigger equipment of light electric vehicle speed control system, and the unit step response curve of dual closed-loop speed control system is given by using the simulation software simulink. A conclusion can be drew that the unit step response quality index of dual closed-loop speed control system is generally good, but the maximum overshoot of this system is relatively large. Considering overall stability, this system should be adjusted. On the basis of these, a double closed-loop speed control system design plan is proposed with rotating speed differential negative feedback, and a rotating speed of negative feedback link is introduced in this system. The simulation results show that the maximum overshoot of this system is reduced by 32.37%, and the overall data shows that this system has excellent stability performance, and also the response speed of this system is guaranteed.
