Lyapunov design under sampling for a synchronous machine

V controllers are well known continuous-time Lyapunov design tools. The object of this work is to discuss their sampled-data versions. Piecewise constant controllers are described in order to provide asymptotic stability and damping at the sampling instants. These sampled-data controllers are tested on a synchronous machine model and their performances are compared through simulations to those obtained via “emulated” strategies.
