“…Where ℛ is the armature resistance, ℓ is the armature inductance, current, is the speed, is the armature voltage, is the motor inertia, and electromotive force (emf) constant, is the motor design constant and Φ is the mo DC motor is joined with the buck converter, the transformation in the inductor c voltage is presented as is the inductor current, E is the voltage supply. While the DC motor model is presented as given in [28]. Lemma 3.…”
