Abstract: In this paper, by means of modern circuit analysis i. e, the network theory analysis, it is based on Newton iteration algorithm for complex nonlinear fluidic circuit, we estabished the linearizing dynamical network-model of equivalent circuit for the fluidic bistable elements and the frequency follower respectively, and established the linearizing dynamical network model of equivalent circuit for the fluidic extreme control circuit. In addition, we were analyzing for the experiment of frequency follower.
