【摘要】 对同步电动机节能原理进行分析,提出一种励磁系统调节的模糊PID控制算法,通过调节励磁电压可改善系统功率因数。在Matlab-Simulink中建立控制系统阶跃仿真模型,仿真结果表明,与常规PID控制方法相比,模糊PID控制有良好的快速跟踪性能和抗干扰性能。更多还原

【Abstract】 By analyzing the basic principle of synchronous motor energy-saving theory, an excitation system control algo- rithm-fuzzy-PID control was proposed. Adjusting the excitation voltage can improve the system power factor. The system step simulation model was made in Matlab-Simulink, and simulation result indicated that fuzzy-PID control is preferable to PID con- trol in respect of fast tracking performance and anti-jamming performance.更多还原
