【Abstract】 In this paper,the implementation of the Direct Torque Control based on TI TMS320 F240 DSP is presented. The control strategy and the software design of DTC are also introduced. A new method to estimate stator flux position of an induction motor is presented. And some new implementation methods to simplify the calculation are also described. The DTC works very well on experiment system based on TI EVM board. The experiment results indicate that this control method can achieve both good dynamic and good steady state performances.更多还原
