Baseline mining method of RR's engine

The nonlinear multiple regression analysis based on kernel function was used to solve the baseline equation of Rolls-Royce's (RR's) engine. The standard kernel function was established and then the deviation model of performance parameters was established. The deviation calculated by factory system was used as target value, and other relevant parameters of the measured values as input, the unknown coefficient could quickly converge and be solved by Gauss-Newton iterative method in nonlinear multiple regression analysis, and the accurate baseline was obtained by ordering the equation. The accurate engine baseline function obtained by the proposed method could satisfy practical application requirements.
