Abstract
Bidirectional control of a DC motor is achieved with standard power transistors and a simple transistorized pre-amplifier. A permanent magnet, DC motor is used as a test vehicle to illustrate the feasibility of control without an amplidyne or mechanical relay. The "bang-bang" capability of the controller to operate as a near-ideal "relay" is emphasized. The inherent flexibility allowed in selecting the switching characteristics is also demonstrated. The discussion points toward practical application and stresses the analysis of the switching characteristics and system performance. The feasibility of using this controller to operate any other type of standard DC motor is also studied.
