Web20 okt. 2024 · In addition, an adaptive linear quadratic regulator was designed in [ 8 ], and the effectiveness of the control strategy was illustrated using a two-degree-of-freedom (2-DOF) helicopter platform. Furthermore, in [ 9 ], a decentralized tracking control was developed for a two-rotor laboratory helicopter based on extended linearization technology. WebYour quadcopter is non-holonomic; it can achieve 6 degrees of freedom, but only by planning maneuvers that make use of its 4 controllable degrees of freedom. You have 6 degrees of freedom. Three translational and three rotational. You have linear movements along the xyz axis and rotations around the xyz axis.
