pmsm.rar - This simulation demonstrates the use of the PMSM in a closed-loop speed and current control on a 1.1 kW 3000 rpm industrial motor. A three-phase motor rated 1.1 KW, 220 V, 3000 rpm is fed by a PWM inverter. In this simulation, the whole system is built entirely with standard Simulink blocks (without resort to blocksets).

dcspeedcontrol.rar - This simulation demonsrtates the control of a dc motor using a speed control and current control loops.Typical dynamic responses od the dc motor are also shown. The motor is initially at standstill and at no load
when a step command in speed is applied when steady-state conditions are reached, a
reversal of speed is commanded followed by a step load application.

dcgen.rar - This simulation illustrates the current and voltage buildup in a self-excited dc shunt generator driven at constant speed.Examine the effects of:
a) changing the residual voltage magnitude and polarity (vres)
b) varying the field resistance Rf =[145 200 250 300 350]
c) varying the load conductance GL=[0.16 0.5 ]
d) changing the field inductance Lf
e) modifying the armature parameters Ra and La
