| Abstract: |
| Based on the introduction of the process of displacement cooking, the key points and difficulties of the control system of displacement cooking were analyzed. Aiming to control the temperature difference between the upper part and the bottom of the digester, the temperature and flow cascade control strategy based on the PSO (Particle Swarm Optimization) algorithm to optimize the parameters of the PID controller was designed. MATLAB/Simulink simulation results showed that the proposed control scheme had the advantages of simple algorithm, fast searching ability and high efficiency, which could effectively realize PID parameter optimization. The results also proved the effectiveness of the proposed scheme. |
