open-loop experiment

基本解释

The control of ignition advance angle is mostly open-loop control and the control data is obtained from experiment. Close-loop control method is applied to avoid engine knock.
对点火提前角的控制主要是开环控制，控制数据由试验得到，对爆震现象采取了闭环控制。
In condition of open-loop, the experiment was performed to make research on range of pressure-adjust, maximum velocity which the load can reach and so on, comparing with theoretical analysis.
对液压变压器应用于垂直负载系统在开环情况下对变压器的调压范围、驱动负载所能达到的最大速度参数等进行了试验研究，并与理论分析进行了比较；
Finally, relative experiments of 3-phase AC motor SVPWM open-loop control are achieved using this experiment platform, the testing result of system comes to the request designed.
最后，在该实验平台上实现了三相交流电动机SVPWM算法的开环控制实验，实验结果表明系统达到了设计要求。
