双馈发电机的TS - PID模糊控制算法仿真研究

摘要

The paper established a dynamic mathematic model for doubly -fed induction generator based on the theory of induction motor. Aiming at conquering the problem of lower robustness and response speed, according to the nonlinear character of doubly-fed induction generator mathematic model, doubly-fed induction generator based on fuzzy control of TS-PID was proposed. By comparing normal PID control with TS-PID fuzzy control, the two control methods were studied in theory. The experiment Results verify that compared with the normal PID, using TS -PID fuzzy control has better robustness and stability, and according to Matlab/Simulink, controlling doubly -fed induction generator based on TS-PID fuzzy control has feasibility and validity.%研究发电机控制器设计优化问题.针对常规PID控制算法鲁棒性差和响应速度低的问题,从电机学基本原理出发,建立了双馈感应发电机的动态数学模型.根据其数学模型的非线性特性,提出了基于TS模型的PID模糊控制算法.在数学建模的基础上,将PID控制算法和TS - PID模糊控制算法用于双馈感应发电机有功功率控制问题中,并对发电机的PID控制器和TS - PID控制器分别进行了仿真.仿真结果表明:采用TS模型的模糊PID控制方法比常规PID具有更大范围的鲁棒性与稳定性.
