摘要
近年来用于脉宽调制(PWM)的单周期控制[1],因结构紧凑、所用元器件少且响应速度快,已得到广泛的重视及应用。探讨了单周期控制用于直流电动机脉宽调速的情况,分别针对开环和闭环控制进行了Simulink仿真,证明该系统稳态调节精度高,动态响应快,由于电路简单、所用元器件少、装置紧凑、可靠性高,不失为轨道交通直流驱动的较佳选择。
One-cycle control （OCC） for PWM has been concerned and applied widely because of compactness, less devices and high speed of response, etc.. The situation in speed regulation with PWM control of DC motor in onecycle control is investigated, the simulink simulation including open-loop and close-loop is carried out successfully. The high accuracy of steady regulation and fast dynamic response are proved. The traffic should be one of best selection because of simple circuit, less devices, compactness and high reliability.
