Method of mass parameter estimation for dynamic system

摘要

PURPOSE: a kind of mass parameter estimation method of dynamic mechanical system estimates that mass parameter is easily and accurately provided to the estimable mass parameter vector of estimation easily and accurately, thus control performance;CONSTITUTION: a kind of relative density vector is converted into estimable form by calculating the relationship and row linearisation model matrix and subordinate factor (S100) of the inearized model of whole removal subordinate factor parameter vector. The estimable of the dynamic mechanical system of the relationship of inearized model is pulled (S200). A kind of dynamic mechanical system of relative density is transformed into estimable form and is estimated (S300). ;The 2013 of copyright KIPO submissions;[Reference numerals] (S110) estimates relationship model equation; (S120) data acquire; (S121) data inputted; (S122) output data; (S130) the trapezoidal shape of line can not be simplified; (S140) determine null matrix by kernel; (S150) the determining combined dynamic parameter of type; (S200) new estimation relationship model equation; (S300) least square technology
