介绍基于数字信号处理器直接转矩模糊控制系统,提出一种采用模糊逻辑在线估算定子电阻的方法,可以提高系统的低速性能和响应。通过观测器对定子磁链和速度估计,采用TMS320F240构成直接转矩模糊控制系统,实验结果表明了该方案的可行性。A system of fuzzy stator direct torque control for induction motor based is introduced. A novel of fuzzy stator resistance estimator on-line is proposed. It can improve the performance at low speeds and the response of the system. By estimating Flux-chain and speed, a fuzzy direct torque control system based on TMS320F240 is made. The experiment result shows that scheme is reliable.
