A multimodel scheme control for a tunnel-diode trigger circuit - extension to the use of butterworth and Chebyshev filters

A multimodel scheme is designed for a tunnel-diode circuit. It improves the transient response in a transition or switching from a system equilibrium point to another one. Each model is obtained by a linearization of the circuit near an equilibrium point. Each of these models can be described as a combination of two other transfer functions describing the plant behavior near two different nominal equilibrium points. The scheme selects online the linear model of the circuit with the best tracking performance in order to generate the control law. Some simulations show the usefulness of this regulation strategy
