Özet

Parameter estimation methods are used to create mathematical models for systems with input and output. In this article, the least squares method (LS) for aircraft is proposed. This method is used to write a realistic equation of the mathematical relationship between physical quantities that vary depending on each other. The parameters of the transfer functions formed as a result of the aircraft mathematical model were estimated with the LS method. Thus, the algorithm of the LS method was created and the results obtained in the MATLAB/Simulink program were shared. As a result of the estimated transfer functions, some aerodynamic coefficients are estimated. In addition, the Integral Square Error (ISE) table has been extracted to see the approximation of the LS method to the real data. this table is also created for transfer functions and aerodynamic parameters. Thus, the error rate of the method was observed.
