The Design And Realization On Direct Torque Control System Of Induction Motor Based On DSP

Direct Torque Control (DTC) is a high dynamic performance speed control system developed after Vector Control Technology in two decades. In this paper, DTC principle is discussed, and control algorithm being suitable to be implemented by DSP is put forward and a fully digital induction motor control system with high performance is developed. The theory basis of this system is DTC technology, and its control center is microprocessor TMS320LF2407. It is designed that power drive circuit composed of MOSFET AC-DC-AC voltage-type inverter and signal sampling. The experimental results prove that the DTC technology has been applied in induction motor successfully .Jiang Yi(Electromotor Control and Energy Economy)Directed by prof. Zhu Ling...
