An Adaptive Command Scaling Method for Incremental Flight Control Allocation
ActuatorsModern aircraft usually employ control allocation to distribute virtual control commands among redundant effectors. Infeasible virtual command can occur frequently due to aggressive maneuvers and limited control authority.

Impact of the ozone monitoring instrument row anomaly on the long-term record of aerosol products [PDF]
Atmospheric Measurement Techniques, 2018 Since about three years after the launch the Ozone Monitoring Instrument (OMI) on the EOS-Aura satellite, the sensor's viewing capability has been affected by what is believed to be an internal obstruction that has reduced OMI's spatial coverage.

Safety-Guaranteed Go-Around Decision Framework Based on Funnel for Automatic Carrier Landing Systems
AerospaceExisting go-around decision methods for Automatic Carrier Landing Systems (ACLSs) are mainly based on altitude deviation. The safe region implied by these methods is therefore effectively single-dimensional, which can lead to overly conservative and ...
