Broad Outline

The use of digital computer methods to control aero gas turbines is comparatively new. The paper attemps to cover their background and essential features in broad outline. It discusses the special properties of digital computer control systems in relation to hydromechanical and electric analog arrangements and the special problems of design and safety involved. Some results of practical tests on a large complex engine are presented and discussed, special emphasis being given to those techniques which are particular to digital systems. The paper finally suggests the directions in which future developments of these systems might move.

Historic Data

This paper establishes the design criteria for the digital computer control systems first produced in 1969, and currently in the tenth year of history for startup, control, and monitoring of combustion turbine units in the 25–125 MW range, reviews the advantages of digital control and the fall-out obtained from the application of an advanced state-of-the-art control in the area of diagnostics and historic data handling, reviews the integration of the digital computer back-up system, composed of a solid-state fuel scheduler and logic sequencer provided for total system performance and reliability, and discusses the feasibility of a computer retrofit using existing software with the latest state-of-the-art microprocessor emulator.

Potential Applications

SummarySome of the unusual factors influencing the choice of digital computer control systems for jet engines are discussed first. The conditions differ in various practical respects from conventional process control applications. Having several identical plants in a typical aircraft and the need for flexibility to keep pace with engine development are of particular importance. Approaching digital control with the traditional process control background may be restrictive in selecting potential applications for the technique.Techniques which can be used with computers to simplify and speed up three aspects of the realisation of a practical system are described briefly. The first of these is the measurement of the actual plant characteristics needed in the analysis of the control system requirements. The second is a method of obtaining good response in the synthesis of a non-linear control function. The third is a technique for programme writing and for simulation used in the verification of the control system behaviour.The techniques described are not in themselves necessarily confined to use with digital control systems and should have value in general use.
