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 一種產(chǎn)生非正弦波的張馳振蕩器,其中,每個(gè)有源器件的輸出端要反饋到另一器件的輸入端以維持振蕩。
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 隨后,采用改進(jìn)型單神經(jīng)元自適應(yīng)pid控制器來消除間隙非線性對(duì)系統(tǒng)的影響,仿真結(jié)果表明所采用的方法能有效消除間隙特性引起的系統(tǒng)自振蕩,并且能夠提高系統(tǒng)的跟蹤精度。
