I was wondering if anyone has any idea about how to solve the following problem.
We are in the process of tuning our quadrotor UAV. We have got it to the stage were it flies reasonably well in manual mode. However, when we switched to altitude mode, the UAV began to drift upwards.
Looking at the flight log, it shows in the Local Position Z graph that the Z setpoint is increasing. However, the Manual Control Inputs graph shows that the throttle starts at below 50% and is decreased, but the Z set-point continues to increase.
Any help would be greatly appreciated.
