摘要/Abstract

摘要： 模型预测控制具有便于植入、可实现多目标跟踪等优点,但是传统的模型预测控制算法开关状态不固定,会降低电流跟踪精度,甚至产生较大的电流纹波.基于此,提出了一种基于模型预测直接功率定频控制(DPCMPC)和滑模(sliding-mode control,SMC)外环控制的双闭环控制方法.利用SMC外环得到系统有功功率的给定值,通过引入零电压矢量改善系统稳态性能,减小功率脉动.为验证理论分析的正确性,构建了完整的仿真与实验测试模型,结果表明该控制方法具有良好的稳态和动态性能.

Abstract: Model predictive control (MPC) has been widely used in grid-connected converter control systems with the advantages, such as easy implantation and multi-target tracking. However, the unfixed switching state of the traditional model predictive control algorithm will reduce the accuracy of current tracking and even produce large current ripple. Therefore, a double closed loop control method based on model predictive direct power fixed frequency control (DPCMPC) and sliding mode control (SMC) is proposed. The SMC outer ring is used to obtain a given value of the active power of the system, and the steady-state performance of the system is improved by introducing a zero voltage vector and the power ripple is reduced. In order to verify the theoretical analysis, a complete simulation and experimental test model was constructed, and the results show that the proposed control method has good steady-state and dynamic performance.

Key words: T-type grid-connected converter, finite set model predictive, sliding mode control, direct power control, fixed frequency control
