Nonlinear Multivariate Spline Based Control Allocation for High Performance Aircraft
High performance flight control systems based on the nonlinear dynamic inversion (NDI) principle require highly accurate models of aircraft aerodynamics. In general, the accuracy of the internal model determines to what degree the system nonlinearities can be canceled; the more accurate the model, the better the cancellation, and with that, the higher the performance of the controller. In this ...
متن کاملAdaptive Quaternion Attitude Control of Aerodynamic Flight Control Vehicles
Conventional quaternion based methods have been extensively employed for spacecraft attitude control where the aerodynamic forces can be neglected. In the presence of aerodynamic forces, the flight attitude control is more complicated due to aerodynamic moments and inertia uncertainties. In this paper, a robust nero-adaptive quat...
متن کاملPeriodic Optimal Trajectories with Singular Control for Aircraft with High Aerodynamic Eeciency
Fuel minimum range cruise of aircraft with high aerodynamic ef-ciency is considered as an optimal periodic control problem. Optimality conditions for trajectories with singular arcs and state variable constraints are derived. Computation of periodic optimal trajectories in the case addressed presents strong requirements on the numerical algorithm. Computational diiculties become larger when aer...
متن کاملAdaptive Sliding Mode Fault Tolerant Control of Civil Aircraft with Separated Uncertainties
In this paper, a sliding mode control algorithm is developed to synthesize nonlinear control system for aircraft systems with actuator faults. Two design parameters are used to deal with uncertainty caused by actuator faults and uncertainty in system dynamics separately. An adaptive algorithm is developed to accomodate these uncertainties without knowing exactly the bounds of these uncertaintie...
متن کاملPredicting Flow Number of Asphalt Mixtures Based on the Marshall Mix design Parameters Using Multivariate Adaptive Regression Spline (MARS)
Rutting is one of the major distresses in the flexible pavements, which is heavily influenced by the asphalt mixtures properties at high temperatures. There are several methods for the characterization of the rutting resistance of asphalt mixtures. Flow number is one of the most important parameters that can be used for the evaluation of rutting. The flow number is measured by the dynamic creep...
