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.
