| 针对目前复合式地源热泵系统控制方法不完善的问题，文中以小型冷却塔辅助地源热泵系统为研究对象，通过响应实验法进行控制器参数整定，利用MATLAB/Simulink软件对其不同运行模式、不同控制算法进行了控制仿真。仿真结果表明：与传统PID控制和模糊PID控制相比，Smith预估PID控制在冷却塔单独运行、地埋管单独运行、二者联合运行3种不同模式下均可以达到较好的控制效果。该控制方法调节精度较高，速度快，超调小，对冷却塔辅助地源热泵系统具有一定的可行性。 |

| In view of currently hybrid ground source heat pump system control method not perfect, the ground source heat pump system with a small cooling tower was researched. The method of response test was used to determine the parameters of controller, and MATLAB/Simulink software was applied for control simulation in different operation model and different control algorithm. The simulation results shows that Smith predictive PID control has a better control effect compared with traditional PID control and fuzzy PID control. This control algorithm is applicable to three different operating modes, such as separate operation of cooling tower, separate operation of ground buried pipes, and joint operation of both. The controller has a high controlling accuracy, fast adjusting speed, small overshoot, it is feasible for ground source heat pump system with cooling tower. |
