The equations for an armature-controlled dc motor follow. The motor’s current is ? and its rotational velocity is ?. ? d? d? = −?? − ??? + ?(?) ? d? d? = −??? − ?? where ?, ?, and ? are the motor’s inductance, resistance, and inertia; ?? and ?? are the torque constant and back-emf constant; ? is a viscous damping constant; and ?(?) is the applied voltage. Use the values ? = 0.8 Ω, ? = 0.003 H, ?? = 0.05 N ⋅ m/A, ?? = 0.05 V ⋅ s/rad, ? = 0, and ? = 8 × 105 kg · m2 . Suppose the applied voltage is 20 V. Use symbolic calculationsto obtain the motor’s speed and current versus time for zero initial conditions. Choose a final time large enough to show the motor’s speed becoming constant.
