System and method using bins to identify gain value(s) of an engage/arrest controller in an aircraft arrestment system

An article of manufacture comprising non-transitory computer storage medium storing computer readable program code which, when executed by a processor implements a method to identify a plurality of gain values of an arrest controller in an aircraft arrestment system, the medium comprising:

• (a) computer readable program code executed by the processor to maintain a plurality of bins, each of the bins associated with at least one gain value in the plurality of gain values and covering an output range of an arrest controller function;
• (b) computer readable program code executed by the processor to dynamically compute an arrest controller function value of the arrest controller function that is dependent on one or more of the following input parameters:
• a port side shaft position θp, a starboard side shaft position θs, an effective skew angle ϕ, an aircraft speed υ, one or more failure/fault flags, an estimated speed of portside shaft of the arrest controller {circumflex over (ω)}ap, and an estimated speed of starboard shaft of the arrest controller {circumflex over (ω)}as;
• (c) computer readable program code executed by the processor to identify a bin within the plurality of bins based on the dynamically computed arrest controller function value in (b);
• (d) computer readable program code executed by the processor to determine, using weighting matrices, at least controller design gain values Kci and Kfi within the one or more gain values of the arrest controller corresponding to the bin identified in (c), wherein controller design gain values Kci and Kfi are picked to shape control loop transfer functions and dampen resonances in the aircraft arrestment system;
• and
• (e) computer readable program code executed by the processor to shape control loop transfer functions and dampen resonances in the aircraft arrestment system by applying the identified controller design gain values Kci and Kfi in (d) in the arrest controller in the aircraft arrestment system.
