The present invention relates to control of engine variable of a gas turbine engine to regulate the surge margins of at least two compressors. A controller (20) receives data measured from engine sensors (22, 23) and uses said data to determine an indication of surge margin for each of at least two compressors (6, 7) of the gas turbine engine. The controller (20) uses the indications of surge margin for each of the compressors to determine a control strategy that balances the requirements of each compressor. In one embodiment a surge margin operating map...
1. An apparatus for controlling a gas turbine engine comprising a plurality of compressors, the apparatus comprising: a controller having an input for receiving at least one measured engine parameter and an output for transmitting control signals for controlling engine variables;wherein the controller is configured to determine, from said at least one measured engine parameter, an indication of surge margin for each of at least two compressors;a surge margin operating map, the surge margin operating map comprising; a first dimension corresponding to the ...
