摘要：本文以永磁同步电动机为基础，研究了直接滑模电流控制策略，该策略对参数变化以及外界干扰的鲁棒性较强，从而广泛应用于电气传动控制领域。设计了新颖的直接滑模电流控制器代替传统的PI电流控制器，并且采用了开关表查询方式加快了动态响应速度。最后基于TMS320DSP28335控制器对永磁同步电动机直接滑模电流控制控制系统进行实验验证，结果表明所设计的控制器动态响应较快，抗干扰能力较强。

Abstract: This paper researched on direct sliding mode current control of a permanent magnet synchronous machine. Due to the robustness to parameters variations and external disturbances, sliding mode controllers were widely used for the control of electrical drives. A novel direct sliding mode current controller was designed to substitute the traditional PI current controller, and switch table was used to speed up the dynamic response. As a result, the experiment of permanent magnet synchronous machine direct sliding mode current control system based on TMS320DSP28335 controller was finished. The experimental results illustrate this designed controller has faster dynamic response and stronger antiinterference ability.
Key words: permanent magnet synchronous machine; direct sliding mode current control; dynamic response; robustness
