The Design of Fuzzy PID Delay Networked Control Systems Based on Genetic Algorithms

摘要

The nonlinear systems with time delay network control is discussed in this paper, transmission delays and packet dropouts for networked control system with random time delay is 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 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 promote reduce transmission delays and packet dropouts.
