摘要
电动车回馈制动的特性对控制策略提出了越来越高的要求,为提高系统的控制精度和响应速度,将零相位误差跟踪控制(ZPETC)引入电动车回馈制动控制中。分析了ZPETC的控制原理,设计电动车回馈制动的ZPETC控制系统,建立了仿真模型并进行仿真分析。仿真结果表明ZPETC可以十分有效地提高电动车回馈制动跟踪效果,将具有广泛的应用前景和实际意义。
The requirement for control strategy of electric vehicle caused by the characteristic of feedback brake becomes higher and higher. In order to improve the control accuracy and response speed, ZPETC is introduced into feedback brake control of electric vehicle. The principle of ZPETC is analyzed, the control system of ZPETC is designed, and simulation model is established, and the simulation analysis is conducted. The result of simulation shows the ZPETC effectively improves the tracking performance of feedback brake of electric vehicle, and it has a comprehensive applicable future and practical significance.
