双重化PWM整流器自抗扰模型预测直接功率控制

Active disturbance rejection control-based model predictive direct power control for dual PWM rectifiers

  • 摘要: 针对车载双重化脉宽调制(pulse width modulation,PWM)整流器控制性能易受到模型不确定性和列车运行条件(输入电压、功率等级、电路参数等)变化影响的问题,提出一种基于自抗扰控制(active disturbance rejection control,ADRC)和模型预测直接功率控制(model predictive direct power control,MPDPC)的双闭环控制算法。其中,外环基于自抗扰控制理论,构建了基于误差驱动的ADRC(error-based ADRC,EADRC)控制器调节直流侧电压;内环结合基于内模原理的功率补偿方案使用两步MPDPC算法实现电流信号的控制。仿真和实验将所提自抗扰模型预测直接功率控制(ADRC-MPDPC)算法与传统基于比例积分的直接功率控制(proportional integral-based direct power control,PI-DPC)算法和PI-MPDPC方法进行对比,结果表明所提策略在系统启动、负载变化及工况切换等场景表现出更优的动态特性和鲁棒性能。

     

    Abstract: There is a problem that the control performance of an on-board dual pulse width modulation(PWM) rectifier is susceptible to model uncertainty and changes in operating conditions of the train, such as input voltage, power level, and circuit parameters, etc. Thus a dual closed-loop control algorithm is proposed based on active disturbance rejection control(ADRC) and model predictive direct power control(MPDPC). An error-driven ADRC(EADRC) controller is constructed based on the ADRC theory in the outer loop to regulate the DC side voltage. The inner loop combines a power compensation scheme based on the internal mode principle with a two-step MPDPC algorithm to control the AC side current signal. Simulations and experiments are conducted to compare the proposed ADRC-MPDPC algorithm with the conventional proportional integral-based direct power control(PI-DPC) algorithm and the PI-MPDPC method, and the results demonstrate that the proposed strategy exhibits superior dynamic characteristics and robustness in scenarios such as system startup, load change, and operating conditions switching.
