| 摘 要： | 针对传统直接转矩控制的缺点,以异步电动机和逆变器的数学模型为基础,将模糊控制理论应用到直接转矩控制系统。使用Matalab软件中的电力系统模块库,建立了模糊直接转矩控制系统模型。基于Matalab/Simulink仿真平台,对此控制系统进行了仿真,并对仿真结果进行了对比分析。结果表明模糊直接转矩控制系统较之传统直接转矩控制系统,能有效改善转矩和磁链的波动,能改善负载阶跃变化时的转矩响应速。

| Abstract: | Against the shortcomings of the traditional DTC, the fuzzy control theory was applied into the DTC based upon the mathematic model of both the synchronous motoe and invertoer. The model of fuzzzy DTC was established by means of the power system bloch of the Mathlab software. The control system was simulated on the platform of Mathlab/imulink and the simulated results showed that the fuzzy DTC had better accuracy, quicker respose and smllaer fluctuation of the magnetic likage than those of the tradition DTC. |
