Lazy global feedbacks for quantized nonlinear event systems
This work addresses control efficiency for nonlinear systems with limited communication, but the results are preliminary and lack concrete performance numbers.
The paper designs a globally stabilizing controller for nonlinear event systems with quantized state information, minimizing control value changes along the feedback trajectory. A heuristic approach is also proposed to reduce computational effort.
We consider nonlinear event systems with quantized state information and design a globally stabilizing controller from which only the minimal required number of control value changes along the feedback trajectory to a given initial condition is transmitted to the plant. In addition, we present a non-optimal heuristic approach which might reduce the number of control value changes and requires a lower computational effort. The constructions are illustrated by two numerical examples.
