Research on temperature control of graphitization furnace with ACDBO optimization fuzzy PID
The temperature control system of graphitization furnace has the characteristics of pure lag,large inertia and nonlinearity.Its mathematical model is difficult to establish accurately,and it is difficult to meet the control requirements by using the traditional PID control method.Aiming at this problem,the fuzzy PID control of adaptive chaotic dung beetle optimization algorithm(ACDBO)is ap-plied to the temperature control of graphitization furnace.Aiming at the problem that the dung beetle algorithm is easy to fall into local optimum,a strategy of using chaotic mapping,adaptive inertia weight and dynamic selection disturbance algorithm is proposed to im-prove the performance of the algorithm.The scale factor and quantization factor of the fuzzy PID controller are optimized to improve its control effect.The results show that the temperature control of graphitization furnace based on fuzzy PID optimized by adaptive chaotic dung beetle algorithm has the advantages of fast heating speed,high control precision,no overshoot and strong anti-interference ability,which greatly improves the temperature control effect of graphitization furnace.
