This paper concerned with the mismatched quantized adaptive security control scheme of Markov jump systems under deception attacks.A quantizer with multi-channel structure is set up at the controller side and each channel has a time-varying mismatch degree.An adaptive update law is designed to estimate the unknown bounds of the cyber-attack.Subsequently,the adaptive security controller consists of three parts is designed.Based on Lyapunov theory and vertex separation technique,the closed-loop system is stochastically boundedness and satisfies the desired H∞ performance.The effectiveness of the proposed scheme is verified by a simulation.
