Simplified state space matrix of a quadcopter
Webb19 sep. 2024 · The matrix R(ϕ, X) describes the rotation around the XB axis for the roll angle ϕ. The rotation result is the body frame with the axes ( XB, YB, ZB ), R(ϕ, X) = [1 0 0 0 cϕ sϕ 0 − sϕ cϕ] E5 Since angular velocities occur around an axis, the angular velocity is not mapped by rotation matrix.
