Temperature control system simulation of bridge air conditioning based on single neuron PID

在使用桥载空调代替飞机机载APU的过程中,对桥载空调的控制成为运行管理中的重点。通过对桥载空调的建模,建立温控系统模型传递函数,为提高温度的控制精度,采取一种改进的单神经元PID控制器,结合传统PID控制方法,并且在单神经元的基础上进行权值与K值的改进,编写S函数,建立被控系统的Simulink模型。用Matlab软件对桥载空调温控系统进行仿真,对比传统PID与改进的单神经元PID的控制效果,仿真结果表明,该改进算法有效地提高了桥载空调系统的快速性与稳定性,具有较好的应用前景。

During the process of using bridge air conditioning instead of airborne APU, controlling of bridge air conditioning has become the focus of operation and management. By modeling the bridge air conditioning, temperature control system transfer function is established. In order to improve the accuracy of the temperature control, an improved single neuron PID controller combined with the traditional PID control method is taken. And on the basis of single neuron, the weight and K value are improved, and the S function is written to establish the Simulink model of controlled system. Matlab is used to simulate the temperature control system of bridge air conditioning system, and the control effect of traditional PID and the improved single neuron PID are compared. Simulation results show that the improved algorithm can effectively improve the speed and stability of bridge air conditioning system, and has good application prospect.
