Research on temperature control system of distillation column based on ABC-PID

Abstract

The existence of non-linearity and variable parameters in distillation column system makes it difficult to tune the parameters of PID controller in its control system. The artificial bee colony algorithm is applied to the temperature control system of distillation column to optimize the PID parameters. The specific process of optimizing PID parameters based on artificial bee colony algorithm is put forward. PID controller optimized by artificial bee colony algorithm and traditional PID controller are separately used to control temperature coupling system of distillation column. The performance comparison and analysis are carried out by simulation. The results show that the temperature response curve of the PID controller based on artificial bee colony algorithm has smaller overshoot and the system has better robustness, verified the superiority of the artificial bee colony algorithm in optimizing the PID controller of distillation column.
