We consider the infinite time linear-quadratic control problem from a behavioral point of view. The performance functional is the integral of a quadratic differential form. A characterization of the stationary trajectories and of the local minima with respect to (left) compact support variations, as well as their relation to stability, are obtained. Finally, several theorems are derived that de...

Sliding mode control is quickly becoming a popular research ...eld due to the several favorable qualities, including robustness. Linear quadratic control has been one of the more popular and more traditional control techniques, partially due to the ease of implementation and its optimality quality. In this paper, we provide an introduction to sliding mode control. A technique is suggested to al...

This paper introduces a linear quadratic control scheme for continuous-time system with observations taken at discrete times. Particular attention is given to the derivation of disturbance terms in model. Control performance may depend critical on accurate forecasts. case building climate control, where solar rays pass through e.g. windows and deliver significant amounts energy dynamics can be ...

<p>In this paper, load frequency regulator based on linear quadratic Gaussian (LQG) is designed for the MAPS with communication delays. The delay considered to denote small time in a local control area of wide-area power system. system modeled state space inclusion matrix parameters. Since some variables are difficult measure real modern multi-area system, Kalman filter used estimate unme...

This paper proposes a discrete-time repetitive optimal control of electrically driven robotic manipulators using an uncertainty estimator. The proposed control method can be used for performing repetitive motion, which covers many industrial applications of robotic manipulators. This kind of control law is in the class of torque-based control in which the joint torques are generated by permanen...

The main challenge for adaptive regulation of linear-quadratic systems is the tradeoff between identification and control. An policy needs to address both estimation unknown dynamics parameters (exploration), as well underlying system (exploitation). To this end, optimism-based methods that bias in favor optimistic approximations true parameter are employed literature. A number asymptotic resul...
