Integrated reconfigurable control allocation

Integrated reconfigurable control allocation

Abstract

This paper presents the development of an integrated reconfigurable control allocation approach. This integrated approach combines frequencyapportioned control allocation with actuator failure detection and isolation. Frequency-apportioned control allocation integrates innovative control effectors with conventional aerodynamic controls and considers both the steady-state performance and frequency response of the individual control effectors. The actuator failure detection and isolation algorithm is a modelbased approach that uses a model of the actuator to predict actuator behavior and an adaptive decision threshold to achieve acceptable false alarm/missed detection rates. This integrated approach provides control reconfiguration when an aircraft is subjected to actuator failure, thereby improving maneuverability and survivability of the degraded aircraft. This paper also addresses system implementation issues. This method is demonstrated on a Lockheed-Martin Innovative Control Effector simulation that has been modified to include a new control effector based on passive porosity. Desktop and real-time piloted simulation results demonstrate the performance of this integrated reconfigurable control allocation approach.
