Abstract : A finite-time passive controller is developed in this paper for Lipschitz nonlinear systems subject to singular perturbation, time-delays, and parameter uncertainties. Based on the singular perturbation theory and passive control theory, a robust passive controller is drafted for the finite-time interval though the unknown and bounded exogenous disturbances. Some sufficient conditions are obtained for the existence of finite-time robust passive controller, which ensures the resulting closed-loop system is finite-time bounded for all allowable uncertainties. A simulation example is provided to illustrate the validity of the proposed controller.
