UNIQUENESS OF LIMIT-CYCLES IN A LIENARD-TYPE SYSTEM

[摘要] In this paper, conditions that guarantee the uniqueness of limit cycles in the Lienard-type system, dx/dt=h(y)-F(x), dy/dt=-g(x), have been discussed. The conditions obtained here are different from those of Zhang and others. Several examples such as x+psi(x)+q(x)rho(x)=0 are given to illustrate that our results may easily be employed in practical applications. (C) 1993 Academic Press, Inc.
