摘要

本篇介紹建物節能H2/H∞控制器整合控制器與無線網路，由Zigbee無線通訊模組擷取場域資訊如室內外的溫濕度與HVAC耗電資訊為回饋控制訊號，H2/H∞控制器是設計具狀態回授估測與最佳回授調節的線性二次高斯（LQG）控制系統。為維持建物舒適的溫度，H2/H∞控制器整合場域量測計算所得之建物熱負載模型與回饋資訊，可即時的調整控制參數設定，在最小耗能下維持舒適的溫度。模擬H2/H∞與PID控制器比較一日耗電量，H2/H∞較PID控制器節能約5.5%。

The energy saving controller in the building was proposed to integrate the H2/H∞ controller and the wireless communication. The Zigbee wireless communication modules acquired the feedback parameters of the field information such as the temperature, humidity and energy consumption. The H2/H∞ controller based on linear quadratic Gaussian (LQG) consisted of a state-feedback estimator and optimal feedback regulator. For maintaining a comfortable temperature in the building, the H2/H∞ controller that combined the heating load model of building with feedback information can appropriately adjust the control parameters to maintain the occupant comfort in minimum energy consumption. The comparison of the simulation results of the H2/H∞ and PID controller showed that the H2/H∞ controller was more energy saving than PID with about 5.5%.
