Research Abstract

We developed the two methods for estimating errors contained in the measured values of flowmeters, considering results of the failure diagnosis method based on control limits. First method was formulated as a quadratic programming problem under constraints of material and component balances using measured values obtained in one steady state. Second method was formulated as an nonlinear optimization problem under constraint of material balance, supposing that errors contained in the measured values don't become smaller and the measured values were obtained in more than one steady states during a long-term continuous operation. The effectiveness of these estimation methods were demonstrated by the numerical simulations with the use of an ethanol plant.
