Description: This book is intended to be an exposition of the modeling and control of
electric machines, specifically, the direct current (DC) machine and the
alternating current (AC) machines consisting of the induction motor, the
permanent magnet (PM) synchronous motor, and the brushless DC motor.
The particular emphasis here is on techniques used for high-performance
applications, that is, applications that require both rapid and precise control
of position, speed, and/or torque. Traditionally, DC motors were reserved
for high-performance applications (positioning systems, rolling mills,
traction drives, etc.) because of their relative ease of control compared to
AC machines. However, with the advances in control methods, computing
capability, and power electronics, AC motors continue to replace DC motors
in high-performance applications. The intent here is to carefully derive
the mathematical models of the AC machines and show how these mathematical
models are used to design control algorithms

Description: In this paper, a comparison is made between different
implementations of the three-level torque comparator
for a Direct Torque Control (DTC) based induction motor
drive. The DTC scheme controls stator flux and torque by
means of hysteresis comparators, respectively a two-level control
structure for the stator flux and a three-level comparator for
the electromagnetic torque. The standard three-level hysteresis
controller has a DC offset torque error. In this paper, an
additive implementation is investigated in order to remove this
DC offset error. The operational principles of the different
implementations are compared based on continuous and discrete
simulation results, which demonstrate the additional advantages
of the additive structure in a discrete implementation of the
control scheme.

Description: A three-phase motor rated 1 kW, 500 Vdc, 3000 rpm is fed by a six step voltage inverter. The inverter is a MOSFET bridge of the SimPowerSystems™ library. A speed regulator is used to control the DC bus voltage. The inverter gates signals are produced by decoding the Hall effect signlas of the motor. The three-phase output of the inverter are applied to the PMSM block s stator windings. The load torque applied to the machine s shaft is first set to 0 and steps to its nominal value (11 N.m) at t = 0.1 s.
Two control loops are used. The inner loop synchronises the inverter gates signals with the electromotive forces. The outer loop controls the motor s speed by varying the DC bus voltage.
