摘要
为了解决空调机组过渡季工况冷热相消的能耗问题,针对表冷器和加湿器建立了基于能量谷优化算法的辨识模型,为了提高能量谷算法的优化性能,采用二阶振荡法融入到能量谷算法中,提高了优化算法的系统辨识精度.采用模糊控制器对表冷器和加湿器阀门开度进行调节,为了提高模糊控制器的控制性能,采用量化系数自动产生更优的模糊规则.仿真实验说明该系统提高了控制精度,控制系统的跟踪性和抗干扰性也得到了提高,使得输出的温湿度快速、准确地逼近设定值,有利于满足生产工艺的需求.
Abstract
To address the cold and hot energy dissipation of air conditioning units during the transitional season,this paper builds an identification model based on the energy valley optimization algorithm for surface coolers and humidifiers.To improve the optimization performance of the energy valley algorithm,the second-order oscillation method is adopted to integrate into the energy valley algorithm.The system identification accuracy of the optimization algorithm is improved.Then,a fuzzy controller is employed to adjust the valve opening of the surface cooler and humidifier.To improve the control performance of the fuzzy controller,the quantization coefficients are used to automatically generate better fuzzy rules.The performances of the control system,including control accuracy,tracking and anti-interference,are improved.Our simulation results show the output temperature and humidity of the control system quickly and accurately approximate the set values,meeting the requirements in the production process.
