摘要
针对高性能电动汽车加速到指定车速过程较慢且车轮打滑的问题,利用双三相永磁同步电机的低压大功率的高性能控制,设计出双三相永磁同步电机TCS/ABS控制系统。首先建立双三相永磁同步电机动力模型和1/4车辆模型,然后分别基于PID控制和模糊控制策略,通过车身速度是否达到目标车速来确定理想滑移率值,最后将此值作控制目标,设计了电动汽车TCS/ABS的闭环控制系统。运用MATLAB/Simulink构建了仿真模型并进行验证,结果表明,控制系统启动时低速阶段能实现滑移率的目标控制,同时能有效避免轮胎打滑,实现高性能电动汽车的短时间快速启动到指定车速巡航,且模糊控制效果更好。
To solve the problem that process is slow and wheel might slip while The high-performance electric car accelerates to a specified speed,dual three-phase permanent magnet synchronous motor TCS/ABS control system was designed,taking advantage of high performance control of low voltage and high power of dual three-phase permanent magnet synchronous motor.Firstly,the dynamic model of dual three-phase permanent magnet synchronous motor and the one-quarter vehicle model were established.Then,based on PID control strategy and fuzzy control strategy respectively,the ideal slip rate value was determined by whether the vehicle body speed reaches the target speed.Finally,this value was considered as the control target and the closed-loop control system of electric vehicle TCS/ABS was designed.MATLAB/Simulink was used to construct the simulation model,and the results show that when the control system starts up at low speed,it can realize the target control of slip rate,effectively avoid tire skidding at the same time,realize the fast start of high-performance electric vehicle to the designated speed of cruise,and the fuzzy control effect is better than PID control.
