基于系统级功率平衡的双PWM变频系统模型预测控制研究
Model Predictive Control Based on the System-level Power Balance Model for Dual-PWM Converters
摘要
Abstract
The research on the technology of the dual-pulse width modulation (PWM) converter system has become a hot issue recently. Based on the model predictive control, a novel power prediction control algorithm was proposed in this paper, in the rectifier side model predictive direct power control was adopted, and in the inverter side model predictive direct torque control was used. Two-step prediction based on the model predictive control (MPC) algorithm was developed to compensate for the delay of a digital control system. Meanwhile, a system-level power balance model was introduced into the DC bus voltage outer loop, and the active power reference was defined based on inverter's output feedback in real-time and periodic power compensation. The excellence of the proposed power prediction scheme was verified by experiments for the induction motor drive system fed by this dual-PWM converter. All the results confirm that the proposed control strategy has improved the dynamic response of the DC link, also effectively inhibited the DC bus voltage fluctuation, and therefore achieved coordinate performance improvement on both rectifier and inverter sides.关键词
