Abstract
Improved propulsion plant control schemes for gas turbine ships can provide both economic and
tactical benefits to the fleet. One way to develope improved propul-
sion controllers is an implementation logic.
to use a marine propulsion emulator as test bed for proposed engine control
This paper describes the development and implementation of a load control system for a marine propulsion emulator which uses a water filled dynamometer and a 160 horsepower gas turbine. Steady state and transient data were collected and analyzed and a dynamic dynamometer model was developed using the Continuous System Modeling Program CSMP III. A proportional plus derivative control
system was designed using the nonlinear CSMP model with a cut-and-try design approach. Hardware control elements including valve positioners and microprocessor interfaces were designed and fabricated. The microprocessor-based controller was programmed with the dynamometer control
algorithm and the system was tested to verify the emulator design.
