Figure 1: Figur 1: Roll of an airplane
An autopilot is to be made that regulates the roll motion of an aircraft.
The goal is for the aircraft's roll motion, o, to follow a reference, pref, affected
by disturbances on the aircraft. The angle is measured with a gyroscope
and compared to the reference Pref. The difference, - Oref, is the input
signal to a regulator with the transfer function hR(S). The output signal from
the regulator, u(t), controls an electrohydraulic servosystem that adjusts the
aileron angle, 0. The electrohydraulic system is described by the equation:
ȧ(t) = k₁ (u(t) – k20(t))
The aileron provides a rolling moment on the aircraft as:
Mr = k30(t)
This moment will cause the aircraft to rotate, changing the roll angle.
The following values are given:
k₁ = 5, k21, k3 10,000
Gyroscope measurement constant: hm
=
140 [V/rad]
Aircraft moment of inertia around the roll axis: J = 50,000 [kgm²]
The aircraft's friction constant against the air in roll motion is: B = 50,000 [kgm²/s]
a) A moment balance around the aircraft's longitudinal axis gives us the
differential equation that describes the aircraft's roll motion. Write down the
differential equations that are part of this dynamic system.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4403d221-625f-467c-8a97-6a5495095eb2%2Fd72ac42f-80bd-4016-bc28-364a26745bcb%2Fqgp6v8j_processed.png&w=3840&q=75)
