Abstract :
In this paper the author presents new Lyapunov and Lagrange stability results for pulse-width-modulated (PWM) feedback systems with type 2 modulation. The linear plant considered herein is assumed to be Hurwitz stable. An optimization procedure is incorporated that improves the stability bounds significantly. The applicability of the present results is demonstrated by means of two specific examples.
