Abstract	This paper mainly presents the controller for networked control system (NCS) with the presence of control transmission time-delay and power compensation at amplifiers firstly. Aiming at the characteristics of time-delay and power compensation, a NCS model with uncertain parameters was established by converting the uncertainties of time-delay and impairment of power. Based on the optical link model, a self-tuning fuzzy controller composed with two fuzzy controllers was proposed. The first-level fuzzy controller was used to solve the influences of the uncertainties on the system stability effectively, and a second-level fuzzy controller was designed to adjust the quantification and the scaling factors of the first-level fuzzy controller in an on-line and adaptive power value according to the changes of inputs at the network nodes. Simulation results that the controller has good dynamic and effective performances for real-time power compensation at the device nodes with NCS time-delay to optical links.
