Based on the success of gas turbine and automotive engine controlsystem designs, a single lever power control (SLPC) model for aircraftpiston engines has been developed utilizing fuzzy logic controllers. Topermit development and refinement of the SLPC controllers, a propulsionsimulation workbench has been developed for simulation of light aircraftpiston engine applications. The objective of the workbench is to providea platform on which the aircraft engine control system modeling anddevelopment can occur. The workbench is an integrated set of MatlabSimulink(R) models of a piston aircraft engine, variablepitch propeller, and controller. In addition, an atmospheric modelsimulates the ambient conditions as they change with aircraft altitude.Results of simulated aircraft missions show dynamic and steady statecharacteristics of both the propulsion system model and single leverpower control system to be acceptable for this application, anddemonstrate the utility of the engine/propeller simulation
