Abstract

PURPOSE: To prevent a high-pressure turbine and a low-pressure turbine from being brought into a hunting condition upon switching of a control signal between a starting control system and a speed control system by providing the control system.
CONSTITUTION: When the signal for the starting control system 8 is selected by a low value gate 11 and is being outputted as a fuel control signal 41, contacts S1W S4 are closed while a contact S5 is opened. In this case, a proportional integral operator 23 is stopped in the integrating operation thereof by the contact S1 and is operated as a proportion operator. On the other hand, the output of a speed setter 21 is grounded by the contact S4. A change rate limiter 33 is inputted with the signal of a low-pressure turbine revolutional number transmitter 12 and supplies the same signal to a subtractor 22 as the output thereof. When the revolutional number of the high-pressure turbine is arrived at the specified value and the starting control is shifted into the speed control, the opening and closing conditions of respective contacts S1WS5 are reversed. According to this operation, a minimum speed preset value is supplied to the change rate limiter 33 from the speed setter 21.
