An infinite /spl epsiv/-bound stabilization design for a class of singularly perturbed systems

According to the Lyapunov stability theorem and the bounds of solutions of the Lyapunov equation, the state feedback gain matrices can be determined to guarantee the stability of the singularly perturbed systems for all /spl epsiv//spl isin/(0,/spl infin/). A numeral example and an operational amplifier circuit are given to illustrate the effectiveness of the proposed scheme.
