改进的Hammerstein系统及其在增压锅炉中的应用
Improved Hammerstein system and its application in supercharged boiler
摘要
Abstract
Aimed at the problem that the Hammerstein models and their improved ones reported until now can only provide limited identification accuracy when applied in the two-input single-output ( TISO) systems, a normalized TISO nonlinear Hammerstein model identification method was proposed and was applied in the nonlinear identification of supercharged boiler combustion process. Nonlinear elements which influence the combustion have different nonlinear hardness at different loads, which make it impossible to acquire an excellent accuracy in the whole range of loads when using only a set of nonlinear parameters for general TISO Hammerstein model. For this reason, the normalized TISO Hammerstein system model was introduced. The results indicate that the proposed method can describe the influence of the two inputs on a system output accurately, which in turns greatly improves the identification accuracy. Also, ideal identification accuracy can be obtained with only one set of locally optimized parameters in a multi-load area, which proves the validity of the proposed method.关键词
