In this Letter, an output error feedback control scheme is addressed for synchronization of a class of non-autonomous chaotic systems based on the drive-response framework. A fuzzy disturbance observer is used to compensate for the difference between the structures of two different systems. To compensate for the uncertainty caused by the unknown phase difference between the drive and the response...
In this paper, non-linear observer-based trajectory tracking control for a wheeled mobile robot is proposed. The non-linear observer is designed for not only an unmeasurable orientation error but current position error. This full-order observer shows robustness to measurement noise. Besides, a controller which exponentially stabilizes the tracking error is used. The non-linear observer with the controller...
In this paper, we consider a new fuzzy stabilizer which has tuning parameter so as to be applicable easily in real nonlinear plants. We adopted Inverse LQ(ILQ) regulator design method in which the state feedback control law is optimal for some unknown weights, thereby simplifying the design procedures. A design procedure is developed to extend the applications of ILQ regulator design method to nonlinear...
The development of unmanned crane is an important issue of factory automation (FA) in steel industry. In slab yard, various kind of slabs(different ingredients, temperature, length, width and thickness and so on) are piled together. When hot slabs were piled and get cold gradually, deformation such as bending of slabs is occurred due to the thermal expansion and contraction. It may make slab to be...
In this paper, we propose a method of computing a improved model predictive control (MPC) law for uncertain state delayed system with unknown bounded delay term and input constraints. The proposed method improves feasibility characteristics and system tracking performance by deriving a sufficient condition for the cost monotonicity using polytope dependent Lyapunov function corresponding to a different...
In this paper, we present a dynamic output feedback Hinfin receding horizon controller for uncertain systems with both norm bound uncertainty and disturbance using new parameter dependent Lyapunov function. This Lyapunov function is proposed to get a less conservative condition and guarantees both closed loop stability and the Hinfinnorm bound. The controller is obtained numerically from the output...
