摘　　要：凝汽器状态评价指标是具有不同量纲的特征参数,为避免对具有不同量纲的特征空间实施无量纲化变换造成的信息失真,隶属度转换模式成为凝汽器状态评价的基本模式.由于特征参数状态渐变连续,所以表征参数状态的指标隶属度是模糊隶属度.模糊隶属度表征模糊状态,模糊隶属度转换实现模糊状态转换.用冗余理论界定模糊隶属度转换的非线性,用非线性去冗算法实现模糊隶属度转换并建立凝汽器状态评价的非线性评价模型.The evaluation indicators of status of condenser are characteristic parameters with different dimensions.In order to avoid information distortion caused by nondimensionalization transformation on characteristic spaces with different dimensions,membership conversion model becomes basic model for evaluation on status of condenser.As the gradient of status of characteristic parameters is continuous,the index membership to represent the status of parameters is fuzzy membership.The fuzzy membership represents fuzzy status and the fuzzy membership conversion achieves conversion of fuzzy status.The paper uses redundant theory to define the nonlinear of fuzzy membership conversion,achieves fuzzy membership conversion in the methods of nonlinear redundant algorithm and constructs nonlinear model for evaluation on status of condenser.
