Reinforcement learning and adaptive dynamic programming for feedback control

TL;DR: This work describes mathematical formulations for reinforcement learning and a practical implementation method known as adaptive dynamic programming that give insight into the design of controllers for man-made engineered systems that both learn and exhibit optimal behavior.

Discrete-Time Nonlinear HJB Solution Using Approximate Dynamic Programming: Convergence Proof

TL;DR: It is shown that HDP converges to the optimal control and the optimal value function that solves the Hamilton-Jacobi-Bellman equation appearing in infinite-horizon discrete-time (DT) nonlinear optimal control.

Reinforcement Learning and Feedback Control: Using Natural Decision Methods to Design Optimal Adaptive Controllers

TL;DR: In this article, the authors describe the use of reinforcement learning to design feedback controllers for discrete and continuous-time dynamical systems that combine features of adaptive control and optimal control, which are not usually designed to be optimal in the sense of minimizing user-prescribed performance functions.

Infinite-dimensional linear systems with unbounded control and observation: a functional analytic approach

TL;DR: In this article, a unified framework for the functional analytic representation of infinite dimensional linear systems with unbounded input and output operators is developed, based on which new results are derived on the wellposedness of feedback systems and on the linear quadratic control problem.

Decay of solutions of wave equations in a bounded region with boundary dissipation

TL;DR: In this article, an energy decay rate was obtained for solutions of wave type equations in a bounded region in Rn whose boundary consists partly of a nontrapping reflecting surface and partly of an energy absorbing surface.
