Aiming at engineering application, parameter selection in conventional PID control of a typical nonlinear plant with time-varying large delay in the complex production technology is a difficult optimization problem, and the Genetic Algorithm(GA) tends to fall into local optimum, the paper put forward a new optimal control strategy of Variable Arguments PID controller. In order to overcome the shortage of the traditional Immune Algorithm and Genetic Algorithm, get a better performance for the variable arguments PID control, this paper, aims to improve several special formulas, such as antibody fitness, expected reproduction probability and selected probability, presents an improved Artificial Immune Algorithm with the elitism reservation and elitism crossover strategy(AIAE). Both computer simulation and field application in nonlinear system with large time delay show that, the variable arguments PID controller based on AIAE has a quite good disturbance resistance and a strong robustness.
