This paper relates the practical and theoretical aspect characterizing the behavioral interactions occurring between modern diesel engines and their associated control systems. The relationships between load and prime mover characteristics are investigated analytically and the implications for governor design and selection identified. The analysis is extended to include the highly nonlinear events that occur during rapid load changes. Simulation is used within this context, and the typical results discussed correspond with trials on a typical high-speed marine diesel engine installation. The importance of the governor-based fuel rack limiting characteristic is also illustrated, leading to an assessment of the implications for any interacting control system such as the load control feature commonly associated with many controllable pitch propeller (CPP) installations. An illustration of microcomputer-based simulation is demonstrated and the role of simulation is discussed with reference to recent sea trial results, recorded during actual maneuvering conditions, involving a slow- speed marine diesel engine. Application of modern simulation software is reviewed in conjunction with associated state-space methods of analysis. It is argued that these techniques, when applied within the governor and propulsion control system context, provide potentially powerful, flexible and reasonable 'user- friendly' tools for multivariable system design.
