Hardware Design Implementation of Direct Torque Control System Based-on TMS320F2808

本文采用TMS320F2808芯片作为控制芯片,完成了一个全数字化直接转矩控制硬件系统,克服了采用TMS320F2407A和TMS320F2812DSP作为直接转矩控制系统的处理器所存在的如抗干扰性、体积方面等诸多不足,给出了电流、电压检测电路实验结果表明,该系统作为无速度传感器直接转矩控制策略的硬件平台,具有电流电压保护措施良好,抗干扰能力强,体积小。

In this paper, TMS320F2808 is used as a master chip. A fully digital direct torque control of hardware systems is finished. The existence of disadvantage such as low anti- interference ability and big size is overcome about TMS320F2407A and TMS320F2812DSP which is used as direct torque control system processors. The current detection circuit and voltage detection circuit is presented. The experimental results show that the system as a speed sensorless direct torque control strategy of the hardware platform,has good current and voltage protection measures, anti-interference ability, small size, strong software portability and so on.
