Abstract :
In practice engineering, some process parameters, which are pivotal to enhance the product ability, can not be monitored online and offline. In this paper, two methods are proposed for monitoring the so-called unmeasured parameters such as level of coal powder in power plant. The first model is nonlinear PLS model based on precise training samples, and the second one is evidential soft sensor model based on imprecise training samples. The results of these two methods are compared.
