* | I finished to implement nonlinear complementary filter on the SO(3). | Hyon Lim (Retina) | 2013-05-29 | 1 | -56/+120 |
| | | | | | | The previous problem was roll,pitch and yaw angle from quaternion. Now it is fixed. 1-2-3 Euler representation is used. Also accelerometer sign change has been applied. | ||||
* | Test flight has been performed with nonlinear SO(3) attitude estimator. | Hyon Lim (Retina) | 2013-05-23 | 1 | -111/+113 |
| | | | | | | | | | | | | Here are few observations: - When the system initialized, roll angle is initially reversed. As filter converged, it becomes normal. - I put a negative sign on roll, yaw. It should naturally has right sign, but I do not know why for now. Let me investigate again. - Gain : I do not know what gain is good for quadrotor flight. Let me take a look Ardupilot gain in the later. Anyway, you can fly with this attitude estimator. | ||||
