Stability analysis of sampled-data control system and its application to electric power market

The stability of sampled-data systems is investigated using a new type of Lyapunov functional. The interval from the sampling point tk to tk+1 is assumed to be a sampling interval. By fully utilizing the characteristic information on the whole sampling interval, a new two-sided closed-loop Lyapunov functional is proposed, which utilizes the information on both the intervals from the sampling point...
