چکیده

A novel model predictive control with state estimator is proposed for polytopic uncertain systems with actuator saturation in which the actuator saturation is described as a convex hull composition. At each sampling time, a state feedback control law is obtained such that the upper bound of the quadratic objective function is minimized. The intrinsic relationship between infinite horizon control problem and finite horizon control problem is derived. And the robust stability of proposed model predictive control is proved. Furthermore, considering the state is partial measurable, a state estimator is designed. And the robust stability criterion for closed-loop system combined controller and estimator is given. Finally, the numerical example demonstrates the effectiveness of the proposed model predictive control with state estimator.

Stabilization of Networked Control Systems with Variable Delays and Saturating Inputs

In this paper, improved conditions for the synthesis of static state-feedback controller are derived to stabilize networked control systems (NCSs) subject to actuator saturation. Both of the data packet latency and dropout which deteriorate the performance of the closed-loop system are considered in the NCS model via variable delays.

In this article, a delay dependent memory robust model predictive control (RMPC) algorithm was proposed for uncertain polytopic state delay systems with input constraints. The state delay is time-varying with an upper and lower bound. We minimize a cost function by minimizing its upper bound for the proposed RMPC algorithm. A new sufficient condition, in accordance with LMI, is presented for co...
