摘要/Abstract

摘要： 为了提高车载充电器动静态性能,以双三相PMSM集成车载充电器模型为研究对象,设计了一种采用积分趋近律的电压电流双环滑模控制策略。该控制策略中电压环快速跟踪直流侧给定电压,电流环稳定交流侧电流,并结合SVPWM技术控制系统在单位功率因数下运行。当系统参数发生变化时,积分趋近律能使电压电流平滑地过渡到稳态,减小稳态误差,削弱系统抖振。搭建仿真模型,与传统PI控制策略比较,验证了该策略在动态性能、抗干扰能力、谐波含量等方面的优势。

Abstract: In order to improve the dynamic and static performance of on-board charger,the dual three-phase PMSM integrated on-board charger model was takenas the research object, and a voltage and current double loop sliding mode control strategy was designed using integral reaching law. In this control strategy, the voltage loop quickly tracked the given voltage of DC side, the current loop stabilized the current of AC side, and the SVPWM technology was combined to control the system to operate under unit power factor. When the system parameters changed, the integral reaching law could make the voltage and current smoothly transit to steady state, reduce the steady-state error and weaken the system chattering. The simulation model was built in simulation software, and compared with the traditional PI control strategy, the advantages of the strategy in dynamic performance, anti-interference ability, total harmonic distortionand so on were verified.

Key words: on-board chargers, double three-phase permanent magnet synchronous motor (PMSM), sliding mode control, integral reaching law
