单片机控制直接转矩系统

Direct Torque Contro1 System with Single Chip Microprocessor

通过直接检测交流电动机定子的电流和电压，实现对交流电动机转矩的直接控制－ 以８０Ｃ１９６ＫＣ单片机作为控制处理器，通过软硬件的设计，制成直接转矩控制系统并进行了试验－ 试验表明该系统使电机转速和转矩波动大为减小，响应速度得到提高－

Direct Torque Contro1 of A.C. Induction motor can be implemented by directly detecting the stator′s current and voltage.The DTC system can be established and tested with a 80C196KC sing1e chip microprocessor and the designed hardware and software.The experiment shows that the vibration of torque is decreased sharply and the response velocity is improved as well It is especially suitable for highly dynamic systems.
