Abstract


The networked non-fragile H control problem for Lipschitz nonlinear system with quantization and packet dropout in both feedback and forward channels is investigated in this paper. The sensor measurement and controller output are quantized by logarithmic quantizers before transmitted over the network. The packet transmissions in the communication channels from the sensor to the controller and from the controller to the actuator are modeled as Markov chains respectively. Based on the Lyapunov functional approach, the networked non-fragile H controller is designed to stabilize the Lipschitz nonlinear system and achieve the prescribed H performance. Finally a numerical example is provided to illustrate the effectiveness of the proposed method.
