Abstract:

A co-design scheme of eventtriggered mechanism and quantized control based on optimal performance for a class of discretetime networked control system(NCS) with resource constrained is proposed. The proposed method can reduce the occupation of network bandwidth by eventtriggered mechanism and also reduce the quantized error by using dynamic quantizer with adjustable zooming parameters, then the NCS is modeled as a discretetime switched system with uncertain parameters. Furthermore, based on the requirement of stability and quadratic performance index, the design problem is converted into an optimization problem with linear matrix inequality (LMI) constraints by using piecewise Lyapunov function and LMI techniques, and the co-design method of corresponding eventtrigger parameter, the adjustable parameter of dynamic quantizer and controller gain is provided to ensure asymptotic stability and minimum quadratic performance index. Finally, we verify the effective of the proposed scheme by simulation.
