Lоng Questiоn 1 (Tоtаl 20 points) Here is а very simplistic model of а sliding door controlled by a dc motor.Motor is attached to a gear box (gear on a linear rack) which converts rotary motion from motor to a linear motion of door. The armature resistance of the motor is R, the armature inductance L=0, the motor torque and back emf constants are both K, and the rotational inertia of the motor’s armature is 0. The torque T of the motor is converted to a force F on door by the gearbox. F = T/r. The angle θ moved by the motor is converted to the position x of the door by the gear box . x = θ*rThe mass of the door is m. The friction is modelled as a damper c. Your ObjectiveFind the transfer function from the motor voltage V to the door position x. TF = Kr/(mRrr*ss + (cRrr + KK)s ) Procedure Complete the Q1 parts below
