Problem-5. The figure below on the left shows an ammature controlled de servomotor driving a load through a gear train, which is commonly used in a closed-loop control system. The schematic diagram below on the right represents the armature circuit rotating simply due to the voltage eat) applied and the fixed magnetic field B by a permanent magnet. The armature voltage as an electrical parameter ea(t) is considered to be the input to the system. The resistance and inductance of the armature circuit are R, and La, respectively. vy(t) is the back emf and directly proportional to the rotational speed of the amature as vy(t) = K m(t), where K, is a constant of proportionality called the back emf constant. The torque developed by the motor is proportional to the armature current, Im(t) = K 4.(t), where K, is the constant of proportionality and called the motor torque constant. When the motor drives a load the equivalent inertia and viscous damping at the armature are )m and Dm, respectively. These entities include the corresponding armature and load parameters.
