Figures & data
Figure 1 The hardware platform, showing (1) the 3-DOF helicopter body, (2) signal conditioning and fan driver interface, (3) National Instruments myDAQ module, (4) control PC, (5) LabVIEW Data acquisition teaching module.
Figure 2 The coordinate system for the 3-DOF helicopter. The elevation, pitch and travel angles, E(t), Ψ(t), Θ(t), respectively, are shown in their positive sense. The fan thrust vectors, F a (t) and F b (t), are also shown.
Figure 3 The block diagram of the system.
