Controller providing linear fluidic control responses to vehicle manoueuvre inputs

A method of controlling a vehicle that is an aircraft, the method comprising:

• receiving a vehicle control input indicating a demanded rate of change of at least one of a heading, attitude, and altitude of the vehicle;
• receiving condition data, said condition data comprising at least one of a pressure of a local fluid outside of the vehicle, a tempereature of the local fluid outside of the vehicle, and a density of the local fluid outside of the vehicle;
• determining a required mass-flow rate required by at least one fluidic control effector to effect the demanded rate of change of the at least one of a heading, attitude and altitude of the vehicle based on the received vehicle control input and the condition data, wherein a relationship between the control fluid mass-flow and the effected rate of change of the at least one of a heading, attitude, and altitude of the vehicle control input is non-linear;
• and
• outputting data relating to the required fluid mass-flow to effect the demanded rate of change of the at least one of a heading, attitude, and altitude of the vehicle.

A non-transient storage medium comprising instructions which, when executed by a controller of at least one fluidic control effector for a vehicle that is an aircraft, cause the controller to:

• receive a vehicle control input indicating a demanded rate of change of at least one of a heading, attitude, and altitude of the vehicle;
• receive condition data, said condition data comprising at least one of a pressure of a local fluid outside of the vehicle, a temperature of the local fluid outside of the vehicle, and a density of the local fluid outside of the vehicle;
• determine a required control fluid mass-flow for the at least one fluid control effector based on the received vehicle control input and the condition data, wherein a relationship between the control fluid mass-flow and the rate of change of the at least one of a heading, attitude and altitude of the vehicle is non-linear;
• and
• output data relating to the determined control fluid mass-flow to effect the demanded rate of change of the at least one of a heading, attitude and altitude of the vehicle.
