【Abstract】 In order to achieve precise adjustment of liquor output flow in white spirit energy saving distillation system, the open-loop transfer function for white spirit energy saving distillation system was established. Based on Simulink, the simulation model of output liquor flow of white spirit energy saving distillation system was built. The parameters of output alcohol flow PID controller are optimized by Drosophila algorithm and Ziegler-Nichols algorithm respectively. The optimization effect of liquor output control performance of white spirit energy saving distillation system under step signal, sinusoidal signal and random signal was analyzed. The results show that: under the step response, based on the fruit fly algorithm, the output liquor flow overshoot is reduced by 1.41%, and the adjustment time is reduced by 0.449 s and the steady-state error is reduced by 0.003 L/min; under sinusoidal excitation, the tracking performance of the system optimized by Drosophila algorithm and Ziegler-Nichols algorithm is better; with the increase of random signal frequency, the fluctuation range based on Drosophila algorithm is small.更多还原
