This study presents LPV H∞ control with an augmented nonlinear observer (ANOB) to improve both the position and yaw tracking errors for Sawyer motors. The proposed method consists of forces torque modulation scheme, ANOB, a Lyapunov-based current controller state feedback guarantee stability error dynamics. ANOB is designed estimate all variables including position, velocity, current, disturban...

This paper is concerned with the problem of H control of fuzzy nonlinear impulsive systems with quantized feedback. New results on the H feedback control are established for one class of fuzzy nonlinear uncertain impulsive systems and one class of fuzzy nonlinear impulsive systems with nonlinear uncertainties by choosing appropriately quantized strategies and applying Lyapunov function approach...

This paper addresses robust H∞ control problems for nonlinear systems with parameter uncertainty. By using the technique of partition of unity, necessary and sufficient conditions for existence of strong robust H∞ dynamic compensators and static state feedback controllers are established in terms of nonlinear matrix inequality (NLMI) approach, respectively. These conditions reduce the robust H∞...

The experimental performance of recently proposed approximation techniques for nonlinear optimal, and nonlinear H 1 control compare favorably with other popular design techniques including LQR, linear H 1 , backstepping, and passivity based control. The performance of the aforementioned six control laws on a physical system similar to the Nonlinear Benchmark problem proposed by Bernstein is com...
