CONSTRAINED PREDICTIVE STRATEGIES FOR FLIGHT CONTROL SYSTEMS

摘要

The complexity of nowadays flight control systemsarises from the engineering prescription toproperly merge and integrate actuators, sensorsand computing units within complex data networkstructures. The use of many different sensorsand actuators, the presence of nonlinear phenomena,dynamic effects due to switching operatingconditions as well as physical constraintsdue to input/state saturations are of paramountrelevance when designing a modern flight controlstrategy, especially in the case of high performanceaircrafts. In this paper we analyzethe effectiveness of recent constrained predictivecontrol strategies when they are used to dealwith specific aircraft control problems. Numericalsimulations are presented on a High AltitudePerformance Demonstrator unmanned air vehicleadopting two different predictive strategies bothdealing with redundant and saturating actuators.
