Abstract
A method and system of controlling a turboprop engine are described. The method comprises obtaining a propeller speed and a pressure-based measurement signal from a torque pressure transducer coupled to the turboprop engine, determining an output power of the turboprop engine from the pressure-based measurement and the propeller speed, calculating a gas generator speed request based on an error between the output power and a reference power, determining a fuel flow command based on the gas generator speed request, and issuing the fuel.

A method of controlling a turboprop engine, the method comprising:
- obtaining a propeller speed and a pressure-based measurement signal from a torque pressure transducer coupled to the turboprop engine;
- determining an output power of the turboprop engine from the pressure-based measurement and the propeller speed;
- calculating a gas generator speed request based on an error between the output power and a reference power;
- determining a fuel flow command based on the gas generator speed request;
- and
- issuing the fuel flow command to fuel control components to control fuel to the turboprop engine.
A system for controlling a turboprop engine, the system comprising:
- at least one processing unit;
- and
- a non-transitory computer readable medium having stored thereon program code executable by the at least one processing unit for:
- obtaining a propeller speed and a pressure-based measurement signal from a torque pressure transducer coupled to the turboprop engine;
- determining an output power of the turboprop engine from the pressure-based measurement and the propeller speed;
- calculating a gas generator speed request based on an error between the output power and a reference power;
- determining a fuel flow command based on the gas generator speed request;
- and
- issuing the fuel flow command to fuel control components to control fuel to the turboprop engine.
