Enhanced LMI Representations for H2 Performance of Polytopic Uncertain Systems: Continuous-time Case

  • Based on two recent results, several new criteria of H2 performance for continuous-time linear systems are established by introducing two slack matrices. When used hi robust analysis of systems with polytopic uncertainties, they can reduce conservatism inherent in the earlier quadratic method and the established parameter-dependent Lyapunov function approach. Two numerical examples are included to illustrate the feasibility and advantage of the proposed representations.
