针对暖通空调HVAC系统中由于存在高度非线性、时变特征以及扰动和不确定性等因素而难以控制的特点，提出基于Takagi-Sugeno(T-S)模糊模型的预测函数控制器设计方法。该方法通过最小二乘辨识算法建立系统的模糊T-S模型，然后基于模糊全局线性化预测模型，采用预测函数控制算法设计系统控制律。仿真实验结果表明该算法是一种跟踪性能好、鲁棒性强的有效控制方法。与常规的PID控制器相比，该方法具有超调量小、调整时间短等优良的动态性能。

In HVAC systems, there exist severe nonlinearity, time-varying nature, disturbances and uncertainty. A novel predictive functional control strategy based on Takagi-Sugeno fuzzy model was developed in order to settie the difficulty to control HVAC systems. The T - S fuzzy model of controlled process was obtained using the least squares method, then basing on the fuzzy T - S global linear predictive model, the process was controlled by the predictive functional control strategy. Finally, the simulation results in HVAC systems control application showed that the proposed fuzzy model predictive functional control approach improves tracking effect and robustness. Compared with the conventional PID control approaches, this FPFC approach has better dynamical performance such as less overshoot and shorter regulation time, etc.
