Abstract |
This paper addresses the design of an observer-based control system for the
one-sided Lipschitz (OSL) nonlinear systems under input saturation. A nonlinear matrix inequality-based control law for the nonlinear systems under input saturation and
unavailable states is derived to ensure convergence of the state vector to the origin. A
decoupling approach is provided for attaining simple design constraints for computing
the controller and observer gains through a cone complementary linearization algorithm.
In contrast to the conventional decoupling methods, the proposed approach considers
OSL nonlinearity and saturation function to demonstrate both the necessity and
sufficiency of the decoupled design constraints for the nonlinear matrix inequality-based
main condition. To the best of our knowledge, observer-based stabilization of OSL
systems under input saturation has been addressed for the first time. Novel results for
the observer-based control of input-constrained Lipschitz nonlinear s
