摘 要: 提出一个椭圆函数L-P方法,适合于具有强非线性的广义VanderPol方程的极限环分析.该法采用椭圆函数代替经典的L-P法中的圆函数.与其它只给出一阶近似解的椭圆函数方法相比,此法给出的近似解具有更高的精确度. An elliptic Lindstedt - Poincare (L - P ) method is presented for the limit cycle analysis of the generalized Van der Pol equations, in which the Jacobian elliptic functions are employed instead of the usual circular functions in the classical L-P perturbation procedure. The solution obtained by this method has much higher accuracy than other elliptic function methods, which gave only first order approximate solution.
