基于电流环解耦的高压电子风扇矢量控制策略
Vector Control Strategy of High-voltage Electronic Fan Based on Current Loop Decoupling
摘要
Abstract
To address mutual coupling between d axis and q axis of the PI current regulator in the per-manent magnet synchronous motor vector control system for high-voltage electronic fans,a voltage feed-forward current loop decoupling-based control strategy was developed.A pre-calculated compensation term was incorporated into the output end of the PI current regulator to achieve an offset between com-pensation term and coupling term.The operation of the high-voltage electronic fan under acceleration,deceleration,sudden load increase,and load decrease conditions was simulated and analyzed.Results demonstrate that compared with the conventional PI control strategy,the proposed strategy achieves a 40.34%improvement in response time,a 51.54%reduction in overshoot,and minimized three-phase current waveform fluctuations,exhibiting superior dynamic performance.关键词
