Unformatted text preview: d) The state-space representation. e) Use Simulink and computer the time response of i a (t) and ϖ r (t) when the armature is stepped zero to 6 V while the change in T L is zero. f) When the motor has reached its steady-state operation under part e), a load torque of 0.5 oz ⋅ in is applied. Compute the time response of i a (t) and ϖ r (t). 1 2. Problem 2: The field current of a dc shunt motor is held constant. a) Express the transfer function G(s) = i α (s)/v α (s) for no-load conditions. b) Show that if B m = 0, this transfer function is identical in form to that of a series RLC circuit. c) Express R, L, and C in terms of machine parameters. 2...
