Abstract: In order to study the way of controlling the large delay object, this paper introduces the chaos ant colony algorithm to the neural network control of large time-delay. It is found that chaos ant colony algorithm is an algorithm that steady astatic, good dynamic performance, and it has certain robustness, but it is also easy to appear stagnation phenomenon in the evolution process. This study constructs an intelligent neural network as a controller through improving the fuzzy PID control. Under this control scheme, improve ant colony algorithm through introducing chaos searching mechanism, and then use it in the off-line optimization of controller's parameters. The experimental results show that the scheme and its optimization strategy can effectively improve the performance of the system.


Keywords: Chaos ant colony optimization, TSP, PID, Large time-delay.
