This paper presents an Hinfin state feedback controller design method for discrete-time piecewise affine (PWA) systems based on a piecewise quadratic Lyapunov function, and the partition information of the PWA systems is taken into account to reduce the design conservatism. Each polytopic operating region is outer approximated by a union of ellipsoids, then the minimum problem of the Hinfin performance...
The design of robust Hinfin controller for a class of uncertain neutral systems with varying state delay and input control delay is considered. The uncertainties are norm-bounded and the states of the uncertain neutral systems are available. Combining the linear matrix inequality with Lyapunov functions by proper assumption, the existent conditions of quadratic stabilization and Hinfin state feedback...
The controller design of the networked control systems with multiple-packet transmission is studied. In controller side a set of observers are used to reconstruct system state, and the state of observer is used as state feedback. Using Lyapunov approach, the sufficient condition of asymptotic stability of closed loop system is proposed, and parametric design method of state feedback control matrix...
In this paper, the problems of relaxed robust quadratic stability conditions for a class of nonlinear systems described by T-S fuzzy model are proposed. Firstly, new quadratic robust stability condition is obtained by designing state feedback controller for T-S fuzzy systems with uncertainties. The condition is represented in the form of linear matrix inequalities (LMIs). Secondly, it presents dynamic...
Based on the robust invariant set, Hinfin controller designing problem for uncertain discrete time-delay system with disturbance and input constraint is considered in this paper. At first, a state feedback controller was designed, when the disturbance belongs to a convex polytope, a control invariant set was derived based on the revised Lyapunov Krasovskii function, and inside this control invariant...
This paper addresses the issue of trajectory tracking control based on a neural network controller for industrial manipulators. A new control scheme is proposed based on neural network technology and linear feedback approach for tracking a planned trajectory. The control system is established with two parallel subsystems designed separately. One is a linear controller based on state feedback with...
