| Abstract: | According to the helicopter mode of an unmanned tilt-rotor,a model based on mechanism modeling was established along with the analysis on its characteristics.Three strategies of position control law were put forward and compared.High precision position control based on ground speed was chosen in the first place.Then,with the physical concept being combined,the internal and external loop parameters were designed in detail from the root locus and time domain step response.The robustness of the control law was verified through nonlinear simulation to complete the designing of longitudinal position control law. |
