碩士 === 元智大學 === 機械工程學系 === 97 === The objective of this research is that the helicopter various models discussion beside, after that is to build a system identification method for the helicopter’s longitudinal/lateral/heave/yaw to be suitable. This paper is different with the domestic identification methods, the use is not the black box(Black Box) or base aerodynamic way to identify parameter, the use is base on flight data and to identify parameter for time domain. This research is application flight simulator and flight computer to make hardware in the loop simulator, research on identification method for Robinson R22 helicopter system, discussion experiment signal’s choice and parameter identification to use method, and system parameter identification for the time domain data of optimization technology, wish to build a system parameter identification technology before helicopter flight in the sky. In numerical simulation result, discovered that the signal choice and to use different method will make identification result difference. The paper will compare identification method to make difference, and proposes suitably system parameter identification method for the helicopter’s longitudinal/lateral/heave/yaw.
