The Field Orientation Principle was fIrst formulated by Haase, in
1968, and Blaschke, in 1970. At that time, their ideas seemed
impractical because of the insufficient means of implementation.
However, in the early eighties, technological advances in static
power converters and microprocessor-based control systems made the
high-performance a. c. drive systems fully feasible. Since then,
hundreds of papers dealing with various aspects of the Field
Orientation Principle have appeared every year in the technical
literature, and numerous commercial high-performance a. c. drives
based on this principle have been developed. The term "vector
control" is often used with regard to these systems. Today, it
seems certain that almost all d. c. industrial drives will be
ousted in the foreseeable future, to be, in major part, superseded
by a. c. drive systems with vector controlled induction motors.
This transition has already been taking place in industries of
developed countries. Vector controlled a. c. drives have been
proven capable of even better dynamic performance than d. c. drive
systems, because of higher allowable speeds and shorter time
constants of a. c. motors. It should be mentioned that the Field
Orientation Principle can be used in control not only of induction
(asynchronous) motors, but of all kinds of synchronous motors as
well. Vector controlled drive systems with the so called brushless
d. c. motors have found many applications in high performance drive
systems, such as machine tools and industrial robots.
