摘　　要：研究新型混合吸收式制冷循环的能量调节的自动控制问题.采用动态矩阵预测控制算法设计多变量动态矩阵控制器,对新型混合吸收式制冷循环的能量进行自动调节,同时利用软件Matlab/Simulink对其进行仿真,结果表明该算法能有效地改善控制器的动态特性,显著提高制冷机的抗干扰性,表现出了较好的自适应能力.Studied was the automatic control of energy regulation in a novel lithium-bromide/water absorption refrigeration cycle with energy storage units. A multivariable dynamic matrix controller was designed by multivariable predictive control algorithm to regulate automatically the energy in the mixed absorption refrigeration cycles. This controller was simulated by Matlab/Simulink. The results of the simulation and on-line use showed that the algorithm is capable of anti-jamming and could improve dynamic characteristics of the absorption refrigeration cycles.
