This paper is concerned with power and rate control for wireless communication networks. Based on the mathematical state-space model establishment of power and rate control system for wireless communication networks with external disturbance, an optimal power and rate control algorithm is presented, and the optimal power and rate control law is derived based on the optimal control theory by solving...
The linear-quadratic optimal disturbance rejection problem by dynamic output feedback for descriptor system is considered in this paper. This dynamic output feedback controller contains two parts: PI observer and state feedback controller. The observer is used to estimate the state variables, and the state feedback controller is to realize the optimization. Firstly, a sufficient condition for the...
This paper deals with the optimal control problem by dynamic output feedback for rectangular descriptor system with disturbance. The design of dynamic output feedback contains two parts. The first one is given to make the rectangular descriptor system to be squared and the poles of the closed-loop system can be placed at arbitrarily approximation to the given positions. The other one is composed of...
This paper presents a new control scheme for NCSs with long network induced time delay. In this method, the controller export multi-value at each sample time, different value for different case of delay. The model of the control scheme has been established. The network induced delay has been discussed and modeled as Markov chain. Using the stochastic optimal control theory, the controller design method...
The optimization and control problem of wet flue gas desulphurization in power plant was studied. Mixed logical dynamics model was built to describe hybrid phenomenon of the WFGD process. Based on the mixed logic dynamics model of WFGD, the predictive control optimization problem was solved using the Mixed Integer Quadratic program (MIQP) solver. Therefore the optimal discrete decision variable (the...
