The parameter values for a certain armature-controlled motor are
KT = Kb = 0.05 N.m/A
c = 0
Ra= 0.8 Ω
La = 3 x 10-3 H
I = 8 x 10-5 kg.m2
Where I include the inertia of the armature and that of the load the load torque is zero. The applied voltage is a trapezoidal function defined as follows.

A trapezoidal profile can be created by adding and subtracting ramp functions starting at different times. Use several Ramp source blocks and Sum blocks in Simulink to create the trapezoidal input. Obtain a plot of the response of ia(t) and ω(t).
