Abstract :
Owing to uncertainties and nonlinearity of high power oil transfer systems and the coupling among inlet pressure, outlet pressure and flow of the pipeline, it is difficult to realize optimal and cooperative control by traditional PID controllers. According to the features of the high power oil transfer system, a novel control strategy that is composed of two fuzzy controllers is proposed in this paper. Based on an improved genetic algorithm, the membership functions and the blending factors are optimized. Simulation results and practical operations show the robustness and effectiveness of the new control strategy.
