英文摘要: |
The control effect of PID control is not ideal in the preheating control system of aseptic brick packaging equipment, this paper presents a new strategy
which is based on the combinations of BP neural network and PID controller. The preheating temperature was based on neuron, allowing PID control parameters to be self adjusted under
supervised learning rules, so as to realize self adjustment when the preheating temperature changed. Using Simulink of asepsis brick package equipment for simulation of preheating
temperature control system, results show that the neuron PID controller in the preheating temperature control system has a good performance. The study improves PID control in the
solution variable parameters and nonlinear problems of shortages, reaching self adjusted goals when preheating temperature changes. |
