AIM
To study and understand the operation of electric drives
controlled from a power
electronic converter and to introduce the design concepts
of controllers.
OBJECTIVES
To understand the stable steady-state
operation and transient dynamics of a motor-load
system.
To study and analyze the operation of
the converter / chopper fed dc drive and to solve
simple problems.
To study and understand the operation
of both classical and modern induction motor drives.
To understand the differences between
synchronous motor drive and induction motor drive
and to learn the basics of permanent magnet synchronous
motor drives.
To analyze and design the current and
speed controllers for a closed loop solid-state DC
motor drive and simulation using a software package
