开关变量 meaning in English
switch variable
Examples
- One - cycle control method is a nonlinear control method . by controlling the switch duty - ratio , it can make the average value of a switched variable equal to or proportional to the control reference in each cycle , so the stationary and transient errors are eliminated
单周控制法是一种非线性控制法，它通过控制开关占空比，使在每个周期内开关变量的平均值与控制参考信号相等或成一定比例，从而消除稳态和瞬态误差。 - One - cycle control technique is conceived to control the duty - ratio d of the switch in real time such that in each cycle the average value of the chopped waveform at the output diode of the switch rectifier is exactly equal or proportioned to the control reference . it can eliminate automatically instantaneous error in every one cycle and the error belonging to the former cycle ca n ' t be brought to next cycle
单周期控制技术的基本思想是控制开关的占空比，在每个周期内强迫开关变量的平均值与控制参量相等或成比例，它能在一个开关周期内自动消除瞬态误差，前一周期的误差不会带到下一周期。 - The distortion introduced by switching power amplifier is typically larger than in their linear counterparts due to intrinsic nonlineariry of switching converter . one of the key factors of affecting fidelity of switching power amplifier is control technique . one cycle control theory developed since 1990s is a large signal nonlinear pwm technology , which basic concept is to force the average of the controlled switch - variable to be equal or proportional to the control reference in each switching cycle . one cycle control technique features the merit of simple circuit structure , high control precision , fast dynamic response , and control performance not affected by the variable of power parameters . it is very suitable to control switching power amplifier
控制技术是影响开关功率放大器保真度的关键因素之一。单周控制理论是20世纪90年代初提出的一种大信号、非线性pwm控制技术，其基本控制思想是保证在每一个开关周期中开关变量与控制参考量相等或成比例。它具有结构简单、控制精度高、响应速度快，控制性能不受电源参数变化影响等优点，因此非常适合于控制开关功率放大器。
