Abstract

This thesis describes a theoretical and experimental programme designed to produce a self optimizing control system to the Differential Compound Engine (DCE). Optimum control surfaces for the relevant variables are obtained experimentally and theoretically and used as the basis for microprocessor control. The system adopted relies on analogue inputs from appropriate transducers to the microprocessor via analogue-to-digital converters with outputs representing optimum control settings implemented via electrohydraulic actuators. An additional theoretical investigation is concerned with further measures to improve efficiency and output torque of the current DCE system particularly through the incorporation of a continuously variable turbine transmission (CVT) and a main drive line torque converter to improve the system. A final theoretical section of the work deals with attempts to determine the best nozzle angle schedule for transient operation, and the application of such a schedule to the calculation of a complete vehicle transient.
