摘要
本文采用文[1]中提出的修正的方法,研究电机工程中一类非线性振动方程,定量地给出了存在极限环的参数范围以及极限环的振幅,并判定该极限环是不稳定的,这些结果与已知的定性分析结果完全一致,从而进一步证实了上述渐近方法的有效性。
In the present paper. we investigate a class of nonlinear oscillation equations in electrical engineering by using the modified Krylov-Bogolyubov method presented in[1].We obtain quantitatively the parameter range for the existence of a limit cycle and the amplitude of Hie limit cycle, and find that the limit cycle is unstable. All the results agree entirely with the known results given by qualitative analysis, hence confirm the effectiveness of the above-mentioned asymptotic method.
