Scheduling of a limited communication channel for optimal control. (Q1428146)

The paper deals with computer control systems with physical bandwidth limitation. Given a continuous-time LQ-controller, the task is to design a sampled-data LQ-controller and a communication sequence such that the performance deviation between the underlying ideal continuous-time LQ-controller and the resulting sampled-data controller is minimal. The optimal schedule is defined as the solution of a combinatorial optimization problem which is solved in a heuristic manner. The scheduling model is periodic. As an example showing how the algorithm works, the authors consider the simultaneous control of two uncoupled inverted pendulums.
