| 摘 要： | 分析研究了常见的几种用于直接转矩控制(DTC)的定子磁链估计方法,对他们的性能做了比较,最终,优化设计了一种基于电压电流(u-i)模型自适应补偿的定子磁链估计方法。通过仿真分析,验证了模型的可行性并优化配置了参数。在此基础上,实际应用于基于TMS320F2812DSP的异步电机直接转矩控制系统实验平台,取得了良好的控制效果。

| Abstract: | Based on the analysis of several common stator flux estimation methods and the comparison of their performances for direct torque control,a way of the stator flux estimation,a voltage and current(u-i) model with self adaptive compensation was designed and optimized.Furthermore,the feasibility of the model was verified and the parameters were optimized through simulation analysis.On this base,the flux estimation model was applied on the induction motor direct torque control system experiment platform based on TMS320F2812DSP,and the high performance of this model is verified by the good control effect on the experiment. |
