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。
In the process of using bridge air conditioners instead of aircraft airborne APUs, the control of bridge air conditioners becomes the focus of operation management. In order to improve the control precision of temperature, an improved single-neuron PID controller is adopted, and the traditional PID control method is combined. Based on the single neuron Carry on the improvement of weight value and K value, write S function, establish the Simulink model of accused system. The Matlab software was used to simulate the temperature control system of the bridge air-conditioners. The simulation results show that the improved algorithm effectively improves the speed and stability of the bridge air-condition system with Better application prospects.
