Popis:	Two methods for the aerodynamic forces conversions from frequency into Laplace domain were conceived and validated: Least Squares LS and Minimum State MS, on the Bombardier CL-604 aircraft. A new feature was added in these two methods consisting in the writing of the error calculated by LS and MS classical methods under an analytical form similar to the LS and MS form of approximated aerodynamic forces; this error was once again minimized. Then, new methods using this new feature were called: Corrected Least Squares CLS and Corrected Minimum State CMS methods (as error was once again corrected). All these four methods were programmed in Matlab to approximate the unsteady aerodynamic forces from frequency domain to Laplace domain.
