Computational Challenges in Flight Control Design

چکیده
The model based design of advanced flight control systems raises many computational challenges both in developing design adequate models as well as in solving optimization based controller tuning and assessment problems. The generation of uncertainty models for aircraft dynamics and the development of low order aeroelastic models are two modelling problems leading to symbolic and numerical computational challenges. Further challenges arise in solving semi-infinite optimization problems for tuning controller parameters or global optimization problems for controller robustness assessment. The satisfactory solution of such problems represents a sine qua non condition for the development of future computer aided design environments for the flight control systems design of the next generation aircraft.

Optimal nonlinear control of flight faults in manned aircrafts in the presence of fault and failure of control actuato
Control actuators' faults are among the major reasons to lose aircraft control while flights. The plane dynamics is severely dependent upon faults and errors in flight control systems and if the reformed control order is not issued by the fault tolerant controller there would be unpleasant outcomes such as inconsistency and the reduction of system performance and some dreadful aerial accide...
متن کاملDesign of Generalized Predictive Control for the Stabilizing Loop from a two-axis Gimbal Seeker, Considering Cross-Coupling in Between two Channels
In this research, Generalized Predictivecontrol (GPC) is proposed for the control of a stabilizing loop from a two axis gimbal seeker. In fact, there are some views about using GPC type controller which are two folds. First, it drives the stabilization loops that are made by a DC motor, Rate Gyro, inertia and cross coupling unit in between two channels using the predictive model type controller...

متن کاملA Multi-Objective Flight Control Approach for Performance Adaptive Aeroelastic Wing
As aircraft wings become much more flexible due to the use of light-weight composites material, adverse aerodynamics at off-design performance can result from changes in wing shapes due to aeroelastic deflections. Increased drag, hence more fuel burn, is a potential consequence. Without means for aeroelastic compensation, the benefit of weight reduction from the use of light-weight material cou...
متن کاملSpecial Issue on Development of Autonomous Unmanned Aerial Vehicles
In support of military operations and civil applications, the Unmanned Aerial Vehicles (UAVs) have quickly emerged as useful and versatile tools with extensive scope of mission profiles. Examples range from small-sized UAVs like Wasp and Black Widow, to medium-sized UAVs like Pioneer and RMAX, to large-sized UAVs like Global Hawk and A160. Flying platforms vary from fixed-wing, rotary-wing, fla...
