15
Motor Modelling switch Load Battery DC Motor T = I L (1) T = K T i(t) (2) i(t) T = Torque I = moment of inertia i(t) = current = angular velocity K T = Constance

16
switch V emf V SS RmRm LmLm i(t) V ss = i(t)R m + Ldi(t)/dt + V emf..........(3) Motor Modelling

17
I L = K T i(t) (2 =3 ) switch V emf V SS RmRm LmLm i(t) di(t)/dt = [V ss -i(t)R m - V emf ]/L (5) Motor Modelling = K T i(t)/I L (4 ) di(t)/dt = [V ss -i(t)R m - K B ]/L (6)

18
I L = K T i(t) (2 =3 ) switch V emf V SS RmRm LmLm i(t) di(t)/dt = [V ss -i(t)R m - V emf ]/L (5) Motor Modelling = K T i(t)/I L (4 ) di(t)/dt = [V ss -i(t)R m - i(t) ]/L (6)
