The design and application of servo systems using stepper motors

Position control systems have for many years been essentially analogue in nature. Developments in stepper motors and semiconductor techniques have resulted in digitisation being possible. This thesis describes the stepper motor, its performance, and its application to position control systems in which the error signal is of a single polarity and a rithiimum value is sought. Systems have been designed and are described which convert the error signal into an angular step of the motor shaft. These principles were then applied to: 1. a simple position servo, 2. a self balancing microwave bridge, 3. control of the damping factor of a larger system.
