Hysteresis is one of the serious defects of piezoelectric ceramics which restraints the precision of an open loop control system. 压电陶瓷的一个重要缺陷是其严重的磁滞现象,制约了开环控制系统的精确性。 www.chemyq.com 2. A control circuit
Theopen loop controlhas not feedback. That means, the control system is not sensitive to aliasing. Thus, this control method is preferred for the system that is nonsensitive and well known with the structure and variables. This method is not preferred for a multivariate system as power network...

题目开环控制(openloopcontrol) 相关知识点: 试题来源: 解析 开环控制是最简单的一种控制方式。它的特点是,按照控制信息传递的路径,控制量与被控制量之间只有前向通路而没有反馈通路。也就是说,控制作用的传递路径不是闭合的,故称为开环。 反馈 收藏 ...
open-loop control[英][ˈəupən lu:p kənˈtrəul][美][ˈopən lup kənˈtrol][电] 开环控制;例句:1.When considering this response it is convenient to look at closed-loop andopen-loop control situations separately.在...
Some applications require the motor to start using an open-loop control. Once the motor achieves the minimum required stability in open-loop control, the control system shifts to closed-loop. In a quadrature encoder-based position sensing system, the motor starts up in open-loop and transitions...

This example uses open-loop control (also known as scalar control or Volts/Hz control) to run a motor. This technique varies the stator voltage and frequency to control the rotor speed without using any feedback from the motor. You can use this technique to check the integrity of t...
