Abstract :
To solve the absolute stability problems of SIMO and MISO systems with several nonlinear time-varying elements, a new conception of isolated part transfer function is introduced. The necessary and sufficient conditions for all the isolated part transfer functions to be positive real are obtained. A conjecture is proposed and a corollary of the conjecture is proved
