英文摘要：

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.
