Parameter Estimation of Airplane Magnetic Model Based on TSVD

Due to multi-collinearity of the airplane magnetic model,it is difficult to estimate the parameters of airplane magnetic model.Therefore,a method of parameter estimation based on truncated singular valve decomposition(TSVD) is proposed.To improve the stability of this method,damping truncated SVD(DTSVD)method is proposed.Simulation result shows that DTSVD has higher stability and precision for parameter estimation.It can be used in engineering application.
