Abstract:

The problem of H∞optimal control is studied for a class of networked control systems with timevarying networkinduced delay and data packet dropout.Given the bound of data packet losses and networkinduced delay, the NCS is modeled as an equivalent system with timevarying delay. By using the LyapunovKrasovskii functional and linear matrix inequality,statefeedback suboptimum and optimum H∞ control laws of NCS are designed based on asymptotical stability. The design of the controller requires neither iterative operation nor the knowledge of tuning parameters.Simulation results verify the validity and feasibility of the method.
