摘　　要：提出了一种带PD输出电压瞬时值反馈内环的内模控制(internal model control,IMC)-PID电压型逆变电源控制方案:PD瞬时值反馈内环提高系统的动态性能,IMC-PID外环保证系统的稳态性能。给出了详细的基于极点配置的内环PD控制器和外环IMC-PID控制器设计步骤和方法。该方案只需检测输出电压,控制器结构简单,分析设计容易。仿真和实验结果表明该控制系统不仅具有优良的动、稳态性能,而且有很强的鲁棒性。相对电压、电流双环控制方案而言,该文提出的方案控制器结构和分析更加简单,成本更低,鲁棒性更强。A novel control scheme with PD output voltage instantaneous-value feedback inner loop for voltage-source inverter is proposed. The inner loop is designed to improve dynamic performance and the IMC-PID external loop can ensure stable performance. The design methods of inner loop PD controller based on pole-assignment and external loop IMc-PID controller are discussed in detail. The control system is very simple and only the output voltage needs to be sampled. The PD inner and IMC-PID external controller are both easy to design and analyse. Simulation and hardware experimental results are given to validate that the control scheme for voltage-source inverter proposed has not only nice dynamic and static performance but also strong robustness. The control scheme proposed has advantage of controller structure, cost and robustness, compared with voltage and current dual-loop control inverter scheme.
