2- An inverted pendulum with a constant rod length of (r) is mechanically fixed to a floor via a DC motor at point P (0,0); see Fig. 4. A flywheel with a mass of (m) and inertia of (1) is attached to the pendulum tip. The motor can generate rotational motion along the a axis, and its output torque is symbolized with (r). The gear and bearings introduce torsional viscous dissipation with a damping coefficient of c. Gravitational acceleration is 9.81 m/s². A torsional spring with a stiffness constant of (k) acts along the a axis. The spring is in rest condition when a = O radians. J = K1/50 = kgm² m = K3 = kg r= K2/4 = c= (K2+K3) / 10 = -. Nms/rad k(spring) = K1*15= Nm/rad Note that K1, K2 and K3 are from Question 0. a=0 m k Fig. 4: An inverted pendulum with o flywheel at the tip. Obtain the mathematical model of the system.
