    摘要:

    基于熱感覺(jué)預測的室內熱環(huán)境自動(dòng)控制方法為解決基于傳統溫度設定值控制不滿(mǎn)足用戶(hù)舒適度問(wèn)題提供新的途徑。但建模過(guò)程中用戶(hù)熱感覺(jué)信息難以獲取,因此開(kāi)發(fā)了便捷的移動(dòng)端智能交互系統以實(shí)時(shí)采集現場(chǎng)數據,建立用戶(hù)學(xué)習樣本;并針對熱舒適的動(dòng)態(tài)變化性特征,設計動(dòng)態(tài)進(jìn)化神經(jīng)模糊推理系統(DENFIS)以建立用戶(hù)熱舒適在線(xiàn)預測模型。通過(guò)實(shí)時(shí)學(xué)習樣本數據驅動(dòng),系統的模糊規則與模型輸出函數系數可動(dòng)態(tài)自校正,推理預測出用戶(hù)偏好溫度。實(shí)驗結果表明所設計的DENFIS算法預測用戶(hù)的舒適溫度范圍準確率高達90.5%,誤差極小。證明了該算法所建立的在線(xiàn)預測模型用于智能空調溫度控制,可解決現有的溫度設定方式帶來(lái)的溫度設定值不合理的問(wèn)題,在實(shí)際應用中具有可行性。

    Abstract:

    The automatic control method of indoor thermal environment based on thermal sensation prediction provides a new approach to solve the problem that the control based on traditional temperature set point does not meet the occupant comfort. However, it is a difficult task to acquire the thermal sensation of occupant during the modeling process. Therefore, a convenient intelligent interactive system of mobile terminal is developed to detect real-time field data to further establish learning samples. In addition, according to the dynamic variability feature of thermal comfort, the dynamic evolving neuro-fuzzy inference system (DENFIS) is designed so that the on-line forecasting model of occupant’s thermal comfort is established. Base on the data-driven of real-time learning samples, the system"s fuzzy rules and the coefficients of model output function can be dynamically self-corrected to predict the occupants’ preference temperature further. The result of experiment shows that the designed DENFIS algorithm predicts the occupant"s comfort temperature range as high as 90.5%, and the error was very small. It is proved that the on-line forecasting model established with the approach can be served as an intelligent air-conditioning temperature controller to solve the problem of unreasonable temperature set caused by the existing temperature set-point method, which is feasible in practical application.
