Creator:: Rodrigues, Terence Keith
Abstract:: The Motor Systems Resource Facility (MSRF) at Oregon State University presently conducts a variety of steady state tests on Motors and Generators, with ratings of upto 300Hp.(225kW), using a dynamometer. The dynamometer consists of an induction motor fed by a power electronic converter. A control computer uses a serial link,...

Abstract:: This thesis presents the development of dynamic control strategies for the brushless doubly-fed machine (BDFM). A simple open-loop scalar controller is first investigated and its response is found to be oscillatory. Using the speed feedback signal, an improved closed loop scalar control algorithm is designed. Steady state performance is controlled...

Abstract:: Environmental concerns have renewed the interest in electric vehicles. To gain widespread use, electric vehicles will also have to offer good performance and be reasonably priced. AC drive systems using modern semiconductors can provide efficient operation at the required power levels, but their cost at present is still too high....

Creator:: Heberle, David D.
Abstract:: A project funded by the Southern California Edison (SCE) Company, Research Center of Irwindale, California, has supported the development of a performance and parameter prediction software program for use during the refurbishment of large synchronous machines, turbine generators, and synchronous condensers. The computer program was developed for SCE to allow...

Creator:: Krishnan, Sheela
Abstract:: The exceptional feature of the brushless doubly-fed machine is the lack of need for frequent replacement of brushes. The inherent instability of this machine has to be overcome for its application in adjustable speed drives and variable speed generation systems. Specific objectives were: to study the characteristics of the machine...

Creator:: Koch, Brian
Abstract:: This thesis presents the development of a supervisory controller for a pre-commercial Brushless Doubly-Fed Machine (BDFM) drive system. In addition, characterizations of new diecast rotors for the BDFM are presented. Using the characterization results from the new rotors, a control scheme was developed to allow a BDFM to be packaged...
