In this paper, the nonlinear systems with time delay network control is discussed transmission delays and packet dropouts for networked control system with random time delay are analyzed. In this paper, online delay estimation method to obtain the delay value, the delay value is an input parameter of fuzzy adaptive PID controller, fuzzy PID temporal adjustment based on genetic algorithm and Particle swarm optimization algorithm to optimization objective function, three parameters of PID is adjusted Online in order to improve the system stability, through Matlab co-simulation tool True Time, the shows the fuzzy logic control system base on PSO algorithm promote reduce transmission delays and packet dropouts. The paper also shows the superiority of Fuzzy PID controllers over their traditional PID for NCS applications.
