摘要:AbstractThe classical LMI framework for robust multi-objective analysis is extended from time-invariant to time-varying systems. Results concern both input-output performances and bounds on time responses such as the damping ratio. State-feedback is considered using the S-variable approach which allows, at the difference of the Lyapunov Shaping Paradigm, to search for several Lyapunov certificates simultaneously, one for each performance requirement of the multi-objective problem.
