TMS320F2808直接转矩控制的变频器设计

Direct Torque Control Converter Based on TMS320F2808

矢量控制需要大量复杂的坐标变换和解耦,难以实时控制。直接转矩控制(Direct Torque Control,DTC)具有结构简单、控制手段直接、信号处理的物理概念明确等优势。本文实现了基于TMS320F2808全数字化直接转矩控制的变频器设计。实验结果表明,所设计的系统具有抗干扰能力强、电压电流的保护措施良好等特点。

Vector control needs a large number of complex coordinate transformation and decoupling; therefore it is difficult to implement real-time control. Direct Torque Control（DTC） has simple structure, direct control means, and clear physical concept of signal processing. A converter is designed based on TMS320F2808 and digital direct torque control. Experimental results show that the system has strong anti-jamming ability and good measures for voltage and current protection.
