スパース性を利用した空調室内機の最適協調制御手法の提案

抄録

The advantage of multi-split packaged air-conditioning system is high operational flexibility and energy efficiency. However, since adjacent indoor units affect each other, the control becomes complex and can cause the deterioration of indoor thermal environment and the increase of energy consumption. Therefore, we propose the cooperative control method that combines MIMO MPC and sparse modeling, here referred to as Sparse MPC, and to verify the proposed method. The results confirmed that Sparse MPC reduces the air conditioning operating time and the number of units in operation. This suggests that Sparse MPC may improve the energy efficiency of air conditioning systems.
