碩士 === 國立成功大學 === 航空太空工程學系 === 89 === System modeling is the base of control. To design a reliable control law, it is needed to have either discrete-time system model or analytical system model. To develop this system model, we have to choose an appropriate identification method in existing identification methods. Constructing RC Model-Helicopter’s model is the main aim of this thesis. The RC Model-Helicopter is a type of aircraft having mobility, worth of researching and potential of application. However, researchers pay more attention on large helicopters than model-scale helicopters. It is worthwhile doing researches on model-scale helicopters. In this thesis, we carry out a system including hardware and software to gather information of helicopter in hovering flight. And using one exiting identification method (Prediction Error Method, PEM) to calculate mathematical model. The model structure used in identification is Black-Box model structure. This mathematical model could be used to be a base of further constructing mathematical model in other flight condition and for hovering control and performance simulation.
