Considering the influence of network time delay,an improved predictive functional control algo-rithm was proposed,which adopts an improved artificial immune genetic algorithm and combines with the elite strategy to calculate primary function’s weighted value;and basing on basic immune algorithm,it employs R similar algorithm to determine both antibody similarity and expectation reproduction rate so as to calculate the selection probability and to effectively inhibit the occurrence of local optimal solution,as well as to keep the diversity of the population and to achieve the purpose of seeking global optimal solution.Simulation results show that this algorithm can ensure stability of the long time delay network control system,and it has good con-trol effect.
