Noise processing of quantized control on CAN network

In quantized control system, the control system performance is degraded by different kinds of noise, but also the noise can make the encoder/decoder pairs overflow. In the latter case, we cannot get the effective information of the state. In this paper, the noise flag method which classifies the different kinds of noise is proposed to make the bound less conservative. The new method solves the problem that the negative influence to control accuracy caused by noises in quantized control. The method also solves the problem of encoder/decoder pairs overflow. Then we verify the BIBO stability of the system and the schedulability of the CAN network.
