On output deviation compensation for systems with quantized input

This paper considers the design of compensator for systems with quantized input in order to reduce the influence of quantization. For systems with (vector) relative degree, we propose a kind of compensator which can compensate for the accumulated output deviation completely caused by quantization. The proposed compensator is capable of keeping the difference of the input-output responses between the system with quantized input and the original system without considering quantization within certain small bound. Simulations show that the proposed compensator can significantly improve the input-output response of systems with both input quantization and packet dropouts.
