Abstract:
The optimization of multifuel boiler operation can save a lot of energy in an integrated iron and steel works.But the identification of efficiency curves of the boilers is a complicated and difficult nonlinear least-squares problem.Considering for reference the hierarchical algorithm for large scale systems,we have developed here anew two-level hierarchical identification algorithm which can transform the nonlinearleast-squares problem into a two-level linear least-squares problem by interaction prediction approach.Simulation results have proved that this algorithm is a very efficientand useful tool.
