    摘要:

    利用傳感器陣列對玉米飲料滋味在模糊信息層面上實現(xiàn)自動化鑒評,。針對玉米飲料滋味感官鑒評的不同剖面引入權(quán)值概念,,利用云模型實現(xiàn)定性定量信息的轉(zhuǎn)換和完成綜合云模型基于權(quán)值差異的調(diào)整,。分析傳感器對玉米飲料滋味感官鑒評甜味,、酸甜味,、入口風味3個剖面的敏感度差異,。在構(gòu)建的模糊神經(jīng)網(wǎng)絡(luò)中,,將針對特定剖面敏感的傳感器陣列采集信息作為輸入,,感官鑒評云模型轉(zhuǎn)化的信息作為輸出,,訓(xùn)練模糊神經(jīng)網(wǎng)絡(luò),以得到的模糊化層中心值,、模糊化層節(jié)點寬度值和模糊決策層調(diào)節(jié)參數(shù)來確定網(wǎng)絡(luò)結(jié)構(gòu),。預(yù)測分析結(jié)果表明,該系統(tǒng)在玉米飲料滋味模糊信息的鑒評過程中,,誤差率在0.00243~0.09177之間,,效果良好。

    Abstract:

    Fuzzy information of corn juices was automatically evaluated based on a sensor array. The concept of weights was introduced for different taste sensory evaluation aspects of corn juices. The conversion of the qualitative and quantitative information was achieved. At the same time, adjustment of a comprehensive cloud model was completed based on the difference of weight. According to the requirements of the different evaluation aspects of corn juices including sweetness, soursweet and flavor, sensor array were analyzed and combination of different sensor array signals were obtained. Fuzzy neural networks were built for prediction of corn juices taste fuzzy information. The information for different aspects collected from sensor array was input. The information from cloud model according to sensory evaluation was output. With training fuzzy neural network, fuzzy layer center value, the fuzzification layer node width values and fuzzy decision-making regulation parameters were obtained to determine the network structure. The forecast analysis showed that the system allowed good effect with 0.00243~0.09177 error rate in the process of automation evaluation of fuzzy information for corn juices.
