摘要 采用内置重复控制器的方法弥补无差拍算法和离散控制系统中的周期性误差,通过对内置重复控制器的设计保证了系统的稳定裕度和稳态准确度。针对内置重复控制器动态性能差的缺点,采用基于空间矢量的滞环控制策略,结合双滞环控制思想,当误差电流落入内环时,使用最优矢量调制得到精确的开关状态;当误差电流落入外环时,使用最快矢量控制迅速减小误差电流到达新的稳态。仿真和实验皆验证了所提出的控制方法具有良好的稳态控制准确度和暂态响应速度。

Abstract:In this paper, a novel method built-in a repetitive controller is put forward to make up periodic error of deadbeat algorithm and discrete control system. The design of the plug-in repetitive controller ensures stability margin and steady precision of the system. Accounting for the poor dynamic performance of repetitive controller, the paper uses hysteresis control strategy based on space vector combined with double hysteresis control thoughts. When the error current falls into the inner ring, the accurate switching state can be obtained by the optimal vector modulation. While when the error current falls into the outer ring, the error current decreases to a new steady state through the fastest vector control. Simulation and experiment results both demonstrate the proposed method has good compensation effect of steady-state control accuracy and improved transient response speed.
