一种具有故障诊断功能的直接转矩控制系统

Direct Torque Control System with Fault Diagnosis

设计了一种具有故障诊断功能的交流异步电机直接转矩控制系统 .介绍了以TMS32 0F2 4 0型数字信号处理器DSP(digitalsignalprocessor)为核心的控制系统的设计方案和软硬件的实现方法 .该系统对电机控制中较常见的故障状态具有有效的排查能力 .

An AC induction motor direct torque control system with DSP-based controller is introduced. The system hardware and software structures, fault diagnosis principle and corresponding testing results are presented. Experimental results show that the developed system has good static, dynamic response and high reliability.
