摘　　要：针对带有外界干扰的多区域空调房间温湿度跟踪控制问题,从建立多区域空调房间的热力学模型出发,在选取稳态工作点对模型进行处理的基础上,提出一种基于多输入多输出状态空间模型的模型预测控制(model predictive control, MPC)策略。设计了多目标优化的性能指标函数,以节约能耗。在matlab中使用mpt3工具箱对控制算法进行验证,在存在干扰的情况下,供气区,工作区,回风区三个区域的温湿度在满足约束的条件下都能较快跟踪上参考值,且鲁棒性较好,验证了所提出的MPC算法有效性与可行性。Aiming at the indoor temperature and humidity tracking control problem of multi-area air-conditioned rooms with external interference, an MPC strategy based on multi-input multi-output state-space model is proposed based on the establishment of a thermodynamic model of multi-area air-conditioned rooms and the selection of steady-state working points for proper processing of the model. The performance index function of multi-objective optimization is designed to save energy consumption. Mpt3 toolbox was used in MATLAB to verify the control algorithm. In the case of interference, the temperature and humidity of the air supply area, working area and return air area could track the reference value quickly under the condition of satisfying the constraints, and the robustness was good, which verified the effectiveness and feasibility of the proposed MPC algorithm.
