Advanced Electric Drives (PDF)

With nearly two-thirds of global electricity consumed by electric
motors, it should come as no surprise that their proper control
represents appreciable energy savings. The efficient use of
electric drives also has far-reaching applications in such areas as
factory automation (robotics), clean transportation
(hybrid-electric vehicles), and renewable (wind and solar) energy
resource management. Advanced Electric Drives utilizes a
physics-based approach to explain the fundamental concepts of
modern electric drive control and its operation under dynamic
conditions. Author Ned Mohan, a decades-long leader in Electrical
Energy Systems (EES) education and research, reveals how the
investment of proper controls, advanced MATLAB and Simulink
simulations, and careful forethought in the design of energy
systems translates to significant savings in energy and dollars.
Offering students a fresh alternative to standard mathematical
treatments of dq-axis transformation of a-b-c phase quantities,
Mohan's unique physics-based approach
"visualizes" a set of representative dq windings along
an orthogonal set of axes and then relates their currents and
voltages to the a-b-c phase quantities. Advanced Electric
Drives is an invaluable resource to facilitate an understanding
of the analysis, control, and modelling of electric machines.
