摘　　要：燃气压缩式热泵空调系统是可充分利用低品位余热的高效环保型建筑冷热联供方案,但又是一个非线性、强耦合、时滞性强的复杂系统,以某种传递函数作为仿真模型分析控制方案的性能尚可,但不能完全了解系统参数的动态变化情况。该文建立了该系统的积分模糊控制方案,并在制热状态下对此控制方案效果进行了仿真。结果表明:该控制模型对于分析控制系统的控制效果、控制作用过程中系统性能的变化规律能够取得比较好的效果,控制方案的动态特性、稳态特性均比较理想。Gas-engine driven heat pump air-condition system is an environmental friendly high efficient heat and cooling severing system using low-stage waste heat. In order to obtain the mechanism of system operation, the new PID-fuzzy controlling method was developed. And the control scheme in the heating condition of the GEHP was simulated. The dynamic simulation results show that the new controlling method is suitable for the system. It has ideal characters of dynamics and stability. The laws of working conditions of the GEHP can be showed perfectly by this controlling method.
