【摘要】 针对目前交流电机配电器控制精度较低,稳定性较差,调节效果不太理想的现状,本着提高电能利用率的原则,介绍一种基于Fuzzy-PID(Fuzzy-ProportionalIntegralDifferential)控制技术的交流电机配电器,通过测量交流电机的功率因数角、电压及电流等参数,经过Fuzzy-PID控制算法的整定,优选出参数Kp,td,ti,进而改变晶闸管导通角,使电机始终处于节电运行状态。该系统运行稳定可靠,可有效地提高电能利用率。更多还原

【Abstract】 As the current distribution devices of induction motor have l ow control precision,worse stability and unideal adjustment effect,a new dist ribution device of induction motor based on Fuzzy-PID(Fuzzy-Proportional Inte gral Differential)control is introduced.With the measured parame-ters of AC m otor,such as power factor angle,voltage and current ,the Fuzzy-PID control a lgorithm optimizes K p ,t d and t i ,and alters conduction angle of thyristor to make AC motor always working u nder electricity-saving conditions.The system operates stably and reliably,an d improves effectively the utilization ratio of electric power.更多还原
