摘要
由于三相三线电压型PWM整流器属于非线性多输入多输出系统,国内外学者已开始将非线性控制理论应用到三相三线电压型PWM整流器控制中,获得不同的非线性控制策略,如反馈线性化、逆系统、滑模变结构、功率控制、无源控制及自抗扰技术。分析了上述非线性控制策略的优、缺点。对于现行的整流器欠驱动控制共性问题,提出以无源控制策略为主、以线性或其他非线性或智能控制策略为辅的综合控制方案,可解决现行非线性控制策略的不足,为进一步研究电压型PWM整流器的控制问题提供借鉴。
Because of multi-input multi-output nonlinearity of three phase three line voltage source PWM rectifier, nonlinear control theory has been applied to the rectifier by scholars at home and abroad to attain nonlinear control strategies of the rectifier including feedback linearization, inverse system, sliding mode variable structure, power control, passivity based control and active disturbance rejection control. The features of nonlinear control strategies of the rectifier are reviewed in the paper. By analyzing common problems of rectifiers with underactuated control, comprehensive control scheme of passivity based control with line control or other nonlinear or intelligent control strategy is proposed in order to overcome the shortages of current nonlinear control strategies and provide references for the control of the rectifier further.
