An electronic control system for regulating the amount of torque applied by a starter/generator to a gas turbine engine during startup. The control system senses engine speed, compares the engine's actual acceleration with a predetermined acceleration, and adjusts the torque to the engine so that the engine accelerates along the predetermined schedule. The predetermined schedule is a function of the engine's speed or time, inlet conditions and oil temperature.

[ What is claimed is:] [1.] A method of starting a gas turbine engine along a preselected start schedule comprising the steps of:providing a starter/generator for driving said engine;sensing engine speed and generating a first signal thereof;sensing elapsed time of the engine start;producing a second signal, in response to said elapsed time, indicative of a predetermined speed for said engine;combining said first and second signals to form an error signal; andadjusting the torque output of said starter/generator in response to said error signal so that said starter/generator only delivers the torque necessary to keep the engine accelerating along the schedule.
