摘要:

三相电压型(Pulse width modulation, PWM)整流器因具有高功率输出、交流侧低电流谐波的特性而被广泛应用于风力发电、新能源汽车等场合。以三相电压型PWM整流器为研究对象,针对传统的模型预测控制(Model predictive PI control, MPPIC)存在算法遍历寻优计算复杂和外环采用PI控制动态响应较慢、抗干扰能力差的问题,设计了模型预测滑模控制(Model predictive sliding mode control, MPSMC)。通过对整流器的工作原理进行分析,建立数学模型,设计了优化的模型预测控制算法,缩短算法的寻优次数,提高了系统稳态性能;同时为了提高系统的鲁棒性,设计了积分滑模控制算法替换外环传统的PI控制。最后,搭建仿真和试验平台,结果得出设计的模型预测滑模控制(MPSMC)相较于传统模型预测PI控制(MPPIC),具有更强的抗扰动能力和更好的动、静态性能。

Abstract:

Three-phase voltage type PWM rectifier with high power output, AC side of low current harmonic characteristics, is widely used in wind power generation, new energy vehicles, and other occasions. Taking the three-phase voltage type PWM rectifier as the research object, the model predictive sliding mode control(MPSMC) is designed for the traditional model predictive PI control(MPPIC), which has the problems of algorithm traversal and optimization computation complexity, and the slower dynamic response and poor anti-interference ability of the outer loop using PI control. By analyzing the working principle of the rectifier and establishing a mathematical model, an optimized model prediction control algorithm is designed to shorten the number of algorithm’s optimization searches and improve the system’s steady-state performance. Meanwhile, in order to improve the robustness of the system, an integral sliding mode control algorithm is designed to replace the traditional PI control of the outer loop. Finally, the simulation and experimental platforms are built, and the results conclude that the designed model predictive sliding mode control(MPSMC) has stronger disturbance resistance and better dynamic and static performances than the conventional model predictive PI control(MPPIC).

Key words: Rectifier, model prediction control, sliding mode control, anti-interference
