DOWNLOAD EBOOK →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seems certain that almost all d. c. industrial drives will be ousted in the foreseeable future, to be, in major part, superseded by a. c. drive systems with vector controlled induction motors.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.

DOWNLOAD EBOOK →In this study, a mathematical dynamic model of an induction motor as influenced by magnetic circuit saturation is developed. Moreover, a modified structure of indirect vector controller scheme is proposed which involves the saturated value of the magnetizing inductance. In order to overcome the disadvantages of the vector control drive system such as speed sensor and parameter sensitivity, two proposed control systems have been developed. In the first system, a simultaneous stator resistance and motor speed estimation based on a modified Model Reference Adaptive System (MRAS) has been used to obtain accurate estimation for motor speed taking the effect of magnetic flux saturation into account. Online magnetizing inductance estimation has been presented to consider the effect of saturation in the proposed system. In the second system, an effective online method for rotor resistance estimation based on a modified MRAS to achieve high-precise control in a wide range of motor speed taking the effect of magnetic circuit saturation into account.
