摘要
通过延时反馈获得了均衡状态下弱非线性瑞利方程极限环的存在条件,并得到位移延时反馈不同于状态反馈,它不仅影响均衡状态下的频率也影响其振幅.最后,利用林濨泰德-庞加莱法求解了Liénard弱非线性型瑞利方程的高阶近似解析表达式.
The steady state condition on limit cycle of nonlinear Rayleigh equation is obtained by using the delayed position feedback in the paper. It is shown that the delayed position feedback is different from other feedbacks, it not only changes the amplitude but also influences the frequency of oscillator. When the limit cycle exists, the high step approximate analysis expression of Liénard weak nonlinear Rayleigh equation is solved by L-P method.
