英文摘要

      In order to explore the application technology of the golden section adaptive control in industrial process control, this paper applies it to the pressure control of water flow pipeline, since the pressure is a common parameter of industrial process control. Using a control experiment platform, a pressure control experiment system of water pump driven by variable frequency speed regulation is built. The adaptability and stability of characteristic modelling and golden section adaptive control are illustrated for this system, and the characteristic model type and control algorithm are determined through analysis. Considering the influence of time delay, a digital extrapolation prediction algorithm is adopted to deal with the pipeline pressure error. The control scheme is simulated and analyzed, and the pipeline pressure control experiments relating to the golden section adaptive control are completed. The experimental results show that the golden section adaptive control can achieve high-precision control of pipeline pressure, and the on-site debugging is simple. The advantages of the proposed control scheme have been verified.
