In this paper, the notion of robust strict QSR-dissipativity is applied to solve static output feedback control problem for a class continuous-time nonlinear rational systems subject input saturation and bounded parametric uncertainties. A local dissipativity condition combined with generalized sector conditions formulate synthesis stabilizing controller in terms linear matrix inequalities. Fur...

In the presence of unknown time-varying disturbances and input saturation, this paper develops a robust nonlinear control law for the dynamic positioning (DP) system of ships using a disturbance observer, an auxiliary dynamic system, and the dynamic surface control (DSC) technique. The disturbance observer is constructed to provide the estimates of unknown time-varying disturbances, the auxilia...

This paper presents neural adaptive control methods for a class of nonlinear systems in the presence of actuator saturation. Backstepping technique is widely used for the control of nonlinear systems. By introducing alternative state variables and implementing state transformation, the system can be reformulated as output feedback of a canonical system, which ensures that the controllers can be...
