Abstract:
A new algorithm is proposed to solve the bilinear data reconciliation problem based on the robust objective function. The data reconciliation problem of bilinear process is transformed into two linear data reconciliation problems with a two-step method. Penalty function is used to transform the constrained optimization problem into the unconstrained optimization problem. The equivalent weight of Huber function and the expression to solve the bilinear robust data reconciliation with the equivalent weight method are given. The upper and lower limits of variables are considered in iterative calculations. Simulation results verify that the proposed method can solve the bilinear robust data reconciliation problem efficiently and decrease the effect of gross errors.
