Nonlinear Control with Limited Information
We consider control problems where the plant and the controller
communicate with each other using a finite alphabet. We discuss recent
results related to the following questions: What is the best communication
protocol for a given control objective? What robustness should the
controller possess in view of the incomplete knowledge of the system
state? How much communication is really needed? The set of relevant
theoretical tools is a blend of nonlinear control, hybrid systems,
Lyapunov stability, and geometric optimization.
