Dynamic Output Feedback Control under Communication Constraints

This paper investigates the stabilization problem for stochastic linear systems with quantized output feedback control, in which sensors, controllers and plants are connected by communication channels. A quantization policy, which relies on changing the sensitivity of the quantizer on the basis of available quantized measurements, is proposed. It is derived that based on the policy, the dynamic output feedback controller can stabilize the unstable plant. Simulation results show the validity of the proposed quantization policy.
