To learn the control methods of general and special purpose electric drives. Supporting their drive task specific optimal selection.
Drive specific and task specific drive controls. Subordinated control structure. Transient equations and block schemes of DC machines.
Line-commutated converter-fed DC drives: block schemes for continuous and discontinuous conduction, circulating current and non-circulating current control for ¼ quadrant and 2/4 quadrant operation. Adaptive current control. Control in field-weakening. 4/4 quadrant DC chopper-fed DC drive with hysteresis and PWM modulator based current control.
Park-vector transient equations of the 3-phase synchronous and induction machines in natural and arbitrary coordinate systems. Equivalent circuits for fluxes and voltages. Torque expressions wit Park-vectors.
Properties of the field-oriented controlled cage rotor induction machine with voltage-source and current-source supply. Dynamic and energy-saving operation. Direct and indirect rotor flux control. Machine models to provide the rotor flux and speed.
Voltage source inverter-fed (VSI) cage rotor induction machine with field oriented control: hysteresis and PWM modulator based control. Direct torque and flux control.
Operation of the double-fed induction machine, its field oriented control.
VSI type grid-side converter: grid-oriented current vector control.
Current source inverter-fed induction motor drive: field oriented control in traditional and PWM operation.
Converter-fed synchronous machine. Optimal control of the machine-side converter, controlling from the shaft and the flux. Step-motor control.
Permanent magnet sinusoidal field synchronous machine drive: normal and field-weakening operation. VSI-fed hysteresis and PWM modulator based current vector control.
Switched reluctance machine drive. Torque calculation, self controlled current control. Control of step motor drives.
