Abstract :
A multimodel scheme is designed for a tunnel-diode circuit with the aim of improving the transient response in a transition or switching from a system equilibrium point to another one. Each model of the circuit is obtained by a linearization of the circuit near an equilibrium point. Moreover, different discretizations for each linear model are considered. A discrete-time controller is parameterized from each of such linearized models in order to match a reference model. The scheme selects online the linear model of the circuit with the best tracking performance to generate the control law. The set of possible linear models of the circuit is updated online during the switching process according to the state of the circuit at some prefixed instants so that a tracking performance index is supervised. A Butterworth second order filter is used as reference transfer function in the simulation
