The Limited Lookahead Control FrameworkThe Limited Lookahead Control Framework
Given a switching hybrid system with state space X and
input set U. The control problem for a set point
specification is to:
· Drive the system from any state in X to a
set-point region Xs in finite time
· Maintain the system in Xs
In the case of utility function specification, the
controller aims to reach the optimal state that
maximizes the system utility.
Application: Signal DetectionApplication: Signal Detection
· Selection of the next step is based on a
map that defines how close the current
