摘要

针对风速的突变性和不确定性，以及开关磁阻发电机的非线性和强耦合性的特点，提出了基于模糊自适应PID闭环控制优化输出电压的方法。介绍了开关磁阻发电机系统的运行原理和模糊自适应PID控制原理，并利用Matlab／Simulink工具分别对常规PID控制和模糊自适应PID控制下开关磁阻发电系统的输出电压进行仿真及对比分析。实验结果表明：模糊自适应PID闭环控制输出电压控制精度更高，动态性能更好，抗干扰能力和鲁棒性较强。%According to the mutability and uncertainty of the wind speed and the nonlinearity and strong coupling characteristics of switched reluctance generators, proposes a method based on fuzzy adaptive PID closed-loop controller to optimize the output voltage. Describes the operating principle of the switched reluctance generator system and fuzzy adaptive PID control principle, and by using Matlab/Simulink tools makes simulation and comparative analysis on the output voltage of switched reluctance generators under the control of conventional PID and fuzzy adaptive PID. The experimental results show that the fuzzy adaptive PID closed-loop control has higher output voltage control accuracy, better dynamic performance as well as strong anti-interference ability and robustness.
