چکیده    In this paper, less conservative conditions for the synthesis of static state-feedback controller are introduced to stabilize networked control systems subject to actuator saturation. both of the data loss and latency which deteriorate the performance of the closed-loop system are modeled as the variable delays. two different techniques are employed to import actuator saturation in the controller design procedure. the novelty of the proposed schemes is to utilize an improved lyapunov-krasovskii functional, free-weight matrix and parameter tuning method to obtain more efficient conditions to determine state-feedback gain for a constrained system which is controlled over the communication network. moreover, optimization problem is formulated in order to find the largest possible estimate for the region of attraction corresponding to maximum allowable delays. numerical examples are presented to demonstrate the outperformance of the suggested approaches compared to the existing results in the literature.
