SYSTEM AND METHOD FOR CONTROLLING ROTORCRAFT
In an embodiment, a method (401) includes: obtaining a first signal from a first sensor of a rotorcraft, the first signal indicating measured angular velocity around a first axis of the rotorcraft (403); filtering the first signal with a lag compensator to estimate angular position around the first...

| description | In an embodiment, a method (401) includes: obtaining a first signal from a first sensor of a rotorcraft, the first signal indicating measured angular velocity around a first axis of the rotorcraft (403); filtering the first signal with a lag compensator to estimate angular position around the first axis of the rotorcraft (405); and adjusting flight control devices of the rotorcraft according to the estimated angular position and the measured angular velocity around the first axis of the rotorcraft, thereby changing flight characteristics of the rotorcraft around the first axis of the rotorcraft. |
