Control gain learners, methods, and programs

摘要

PROBLEM TO BE SOLVED: To learn a control gain for controlling an air conditioner. SOLUTION: Control gain learning for learning a control gain set in a control device for controlling an opening degree of an expansion valve of the air conditioner so that the suction temperature of a compressor included in the air conditioner approaches a target value. An evaluation unit for evaluating the fluctuation value of the suction temperature detected by the control device controlling the opening degree of the expansion valve based on the control gain set in the first period, and the above-mentioned device. A learning unit for learning the control gain to be set in the second period according to the state of the air conditioner in the first period is provided, and the learning unit is based on the result of evaluation by the evaluation unit. , The control gain to be set in the second period is learned.
