An electric servo motor drives a rotary motion axis. The rotary load is directly co motor shaft. There is no any gear reducer between them. The rotary load is a solid cylindrical shape made of steel material whose mass moment of inertia is 0,1 kg/m2. The desired motion of the load is a periodic motion. The total distance to be traveled is 7/8 of a revolution. The period of motion is teyc = 5ta ms, and the dwell portion of it is tw = 2t, ms, and the remaining part of the cycle time is equally divided between acceleration, constant speed, and deceleration periods, ta = t, = ta = 100 ms. Angular speed vs time graph is given. Assume that the rotor inertia and the load inertia are equal to each other. Speed
