Direct digital speed control system for a DC motor using a minicomputer

Creator:: Evans, Donald LeRoy
Abstract:: Direct digital control is becoming quite common in the control of industrial processes. However, due to the relatively high accuracy of both analog and conventional digital systems for controlling the speed of a dc motor, there has been a reluctance to try DDC for this purpose. This thesis describes a...

Prediction of brushless DC drive performance considering non-sinusoidal parameter variations and asymmetrical operating conditions

Creator:: Spee, Rene
Abstract:: A highly flexible numerical simulation model for the performance prediction of brushless dc drives is presented, which is capable of investigating unbalanced and asymmetrical operating conditions as well as drives with non-ideal parameters. Numerical speed-up procedures allow for the investigation of pulse-width modulated (PWM) drives using a personal computer. Experimental...

DC bus capacitor discharge of permanent magnet synchronous machine drive systems for hybrid/electric vehicles

Creator:: Jin, Lei
Abstract:: Permanent magnet synchronous machines (PMSMs) are widely used in electric vehicles and hybrid electric vehicles to propel the wheels. Various control strategies have been developed for PMSM drive systems to achieve both high efficiency and safe operation. In a PMSM drive system, generally the high voltage battery and the power...

The Design and Construction of a 5 K.W., D. C. generator

Creator:: Gilkey, Jesse Smart and Chapman, Alexander Kesterson
Abstract:: Since this treatise is to deal only with the construction of one special machine it is unnecessary to go into an extended discussion of dynamo electric machinery in general. Some of the parts common to all electric machinery of this character will be mentioned and then a short account of...

The theory, design, and construction of a 5 k.w., 125 volt, compounded, direct current generator

Creator:: Wiggen, Eugene Cyrus and Baker, Walter Rawalt
Abstract:: It has been a standing problem among the scientists of the past and will perhaps be puzzled-over for many centuries to come; namely the most efficient method of transmitting power from one point to another. The nearest solution at present, and a very satisfactory one, is electricity. By means of...

Construction and Operation of a Direct Current Compound Wound Generator

Creator:: Crowe, Elmer Raymond and Howard, Charles Harry
Abstract:: Electricity is the name given to an invisible agent known to us only by its attendant phenomena and by various manifestations called electrical. These manifestations, at first obscure and even mysterious, are now well understood. Indeed its great importance to mankind can only be realized when we remember that it...

Digital simulation of a self-excited cumulative compound direct-current generator with variable load

Creator:: Maraqa, Abdel Muti
Abstract:: This thesis develops a simulation model for a cumulative connected compound direct-current generator to varify the operation of this machine under conditions of slowly and rapidly changing loads. The application of this simulation method will contribute to more exact modeling of power system components. The accuracy gained is in the...

Real time predictive control of generating system using hybrid computer and a fast time adaptive model

Creator:: Heuch, Knut
Abstract:: A system consisting of two d-c generators, one exiting the other, is controlled with an EAI 690 hybrid computer in an on-line operation. The hybrid computer works as a predictive controller with an on-off actuating signal. A fast-time, second-order model is used to determine the switching time, and a small...

Real-time predictive voltage control of a direct-current generating system, using a hybrid computer

Creator:: Nehrir, Mohammad Hashem
Abstract:: Real-time predictive voltage control of a direct-current (d-c) generating system is achieved with the aid of a hybrid computer. Some assumptions were required to adequately simplify the simulation of the d-c generating system. A predictive controller is used to maintain the load voltage of the d-c generating system (the controlled...
