Quanser 3 DOF Helicopter Experiment

Controls Research Plant

3 DOF Helicopter Controls Research Plant—The Quanser 3 DOF Helicopter Experiment features a model helicopter body, a metal base, and an aluminum frame. The helicopter has two propellers mounted in parallel to each that are actuated by DC motors. The helicopter body is suspended from an instrumented joint that is mounted at the end of a long arm. The other end of the arm is fastened to the base using a two-degree-of-freedom joint. This allows the arm and the helicopter to be rotated about the vertical axis and the elevation axis. All axes are measured using high-resolution encoders to obtain precise position feedback. The Quanser 3 DOF Helicopter Experiment system exposes students to more advanced flight dynamics concepts by extending control to three axes (travel, yaw, and pitch).
