Patent number: 11117650Abstract: A control system (200) using fixed point computation avoids overflow conditions by limiting the internal quantities ensuring that contributing calculations from various parts of the control loop never add up to an overflow. Various parts of a control loop e.g. proportional terms can be prioritised over other parts, e.g. integral and differential terms and ensuring that the overall total resulting when the separate terms are summed together never exceeds the maximum or minimum imposed limits. Variable limit calculator circuits (211,219) revise the limits according to the output of the higher priority control path(s). The revised limits cascade down through each contributor, eventually allowing the lowest priority control path the smallest authority. The control system may be applied to control of a drive motor (111) for an aircraft inceptor (103).Type: GrantFiled: July 13, 2017Date of Patent: September 14, 2021Assignee: BAE SYSTEMS plcInventors: Justin Mark Dee, Jason Howard Bean

Patent number: 11112860Abstract: A method and apparatus are provided for determining the orientation of an object relative to a platform likely to be exposed to buffeting. The object may be a helmet worn by a pilot in which orientation of the helmet relative the aircraft while in flight may usefully be known, in particular when determining the position of space-stabilised symbols being displayed in an associated helmet-mounted digital display system. According to the method, not only may orientation of an object may be predicted at some time ahead of a time point of validity of source sensor data, but the prediction may be dynamically configured to according to a detected severity of buffeting to reduce the effects of the buffeting upon the quality of data output by the system. The method includes measuring the severity of any buffeting using the same source data as used to determine orientation of the object.Type: GrantFiled: September 12, 2016Date of Patent: September 7, 2021Assignee: BAE SYSTEMS PLCInventors: Simon Trythall, John Richard Williams, Peter Michael Knight
