Distributed approach to electronic engine control for gas turbine engines
First Claim
1. A distributed electronic engine control system comprising:
- an airframe module, an electronic engine control module, and an engine I/O module, the modules arranged in locations remote from one another, each of the modules removably secured to a docking station at each of the locations;
a serial communications bus interconnecting the modules with one another;
a first engine controls device connected to the engine I/O module and configured to interact with an engine component and provide a first data; and
wherein the engine I/O module includes inner loop control logic using the first data and producing a second data in response thereto, the electronic engine control module including an outer loop control logic using the second data and producing a third data in response thereto, the airframe module receiving power and distributing the power to the electronic engine control and engine I/O modules, the first, second and third data provided on the serial communications bus.

Abstract
A distributed electronic engine control system includes an airframe module, an electronic engine control module, and an engine I/O module. The modules are arranged in locations remote from one another. A serial communications bus interconnects the modules with one another. A first engine controls device is connected to the engine I/O module and is configured to interact with an engine component and provide a first data. The engine I/O module includes inner loop control logic that uses the first data and produces a second data in response thereto. The electronic engine control module includes an outer loop control logic using the second data and produces a third data in response thereto. The airframe module receives power and distributes the power to the electronic engine control and engine I/O modules. The first, second and third data are provided on the serial communications bus.

17. A method of controlling a gas turbine engine comprising:
-
a) receiving data in an engine I/O module from at least one of a engine sensor and an engine effector; b) manipulating the first data with an inner loop control logic residing in the engine I/O module to produce a second data; c) broadcasting the first and second data over a serial communications bus; d) receiving the second data from the serial communications bus in an electronic engine control module located remotely from the engine I/O module, the electronic engine control module including an outer loop control logic; e) manipulating the second data with the outer control loop logic to produce a third data corresponding to a command signal; f) broadcasting the command signal over the serial communications bus; and g) receiving the command signal from the serial communications bus in the engine I/O module and commanding an engine controls device based upon the command signal. - View Dependent Claims (18, 19)
