摘要

基于电流反馈调制的程序提供最快的响应，并提供准确的电流控制，没有跟踪错误。本文提出的两种调制方法都是在固定频率时钟信号给出的恒定采样频率下工作的。如果将采样信号每相位移动1/3的采样周期，就可以实现电压空间相量的顺序运动，从而保证只有相邻和零电压矢量的选择。作为笼型感应电动机驱动的转子场定向矢量控制结构的一部分，对所提出的技术进行了仿真验证。

Current-Feedback Control at Constant Sampling Frequency Applied in Rotor -Field-Oriented Induction Machine Drives

Current-feedback modulation based procedures offer the fastest response and provide accurate current control, without tracking errors. The two modulation procedures presented in this paper are working with constant sampling frequency given by a fixed frequency clock signal. Sequential motion of the voltage space phasor can be achieved if the sampling signal is shifted with 1/3 of the sampling period for each phase, that will guarantee only adjacent and zero voltage vector selection. The proposed techniques were tested by simulation as part of a rotor-field oriented vector control structure for a cage induction motor drive.
