摘要:
分析电压输出滞后、电流采样延时和交直轴(d-q轴)电压耦合等制约电流环带宽提高的因素,提出一种复矢量解耦的电流环预测控制算法.采用电流环预测控制算法提高电流环响应;对当前时刻电流进行采样,得到下一时刻的电压,减少电流采样延时;采用占空比双次刷新控制算法缩短电压输出滞后时间;采用复矢量解耦的方法解决d-q轴电压耦合问题,进一步提高电流环性能.结果表明:相较于比例-积分控制算法,文中方法具有更优的电流环响应性能.
Abstract:
Based on the analysis of voltage output lag, current sampling delay and direct-quadrature axis(d-q axis)voltage coupling which restrict the improvement of the current loop bandwidth, a complex vector decoupling current loop predictive control algorithm is proposed. The current loop predictive control algorithm is used to improve the current loop response. The current is sampled at the current moment to obtain the voltage at the next moment to reduce the delay of current sampling. The duty cycle double refresh control algorithm is adopted to shorten voltage output lag time. The complex vector decoupling method is used to solve the voltage coupling problem of d-q axis to further improve the performance of current loop. The results show that the proposed method has better current loop response performance than proportional-integral control algorithm.
