sustained oscillation meaning in English

持续振荡
持续振动
自持振荡

A type of relaxation oscillator used for the generation of nonsinusoidal waves in which the output of each active device is coupled back to the input of the other to sustain oscillations
一种产生非正弦波的张驰振荡器，其中，每个有源器件的输出端要反馈到另一器件的输入端以维持振荡。
Aim to eliminate the influences of backlash nonlinear characteristics , a second generation adaptive pid controller based on single neuron is given . the result of simulation and the debug of actual digital servo system shows that the controller can effectively get rid of the sustained oscillation of the system caused by the backlash characteristics , and can improve the system accuracy
随后，采用改进型单神经元自适应pid控制器来消除间隙非线性对系统的影响，仿真结果表明所采用的方法能有效消除间隙特性引起的系统自振荡，并且能够提高系统的跟踪精度。
