The Use of Neural Networks Adaptive Control in Airconditioning System

In this paper,neural networks adaptive control is used to solve the problem of great inertia and great delay in air-conditioning system and to improve the control effect.An algorithm is proposed based on neural networks adaptive control.Two BP neural networks,NNC and NNI,working respectively as controller and identification,can solve the problem of the temperature control in the terminal installment of variable amount of wind air-conditioning system by means of mutually erroneous transmission,gathering correlative output,monitoring the work state of the system and regulating the real-time parameter of neural networks controller.Neural networks identification can make the air conditioning working state good,realizing intelligent control in air-conditioning system.The simulative result indicates that the system has good dynamic performance and stable performance.We can conclude that neural network adaptive control is better than conventional controller,with the characteristics of quick adjustable speed,small overshoot and good control performance.
