The aerospace relay is an important part of the complex electronic systems in large-scale structural components, such as launch vehicle, and its working state determines whether system can work properly. Due to lack high-value samples, complexity system, multiple environment disturbance factors affecting relay, this study, we developed a new fault diagnosis tolerance control framework for based...

Abstract Considering the precise model information of aerospace is not always available under effect external disturbance and uncertainty, a new data‐driven point‐to‐point iterative learning control (PTPILC) method proposed for vehicles to track predetermined trajectory. Firstly, system vehicle converted into discrete form without any omission, which reflects dynamics original by input output d...

The use of genetic algorithms for solving aerospace control system design and optimization problems is investigated. A modified genetic algorithm based on floating point representation of the chromosome and appropriate genetic operators is developed and used to design controller gains for an autonomous airvehicle. The controller design problem is formulated along a classical pattern with requir...

Unmanned air systems are becoming increasingly pervasive in academia as well as industry. Aerospace research and education have to-date focused on the fundamental aerodynamics, structures, and control technologies required for these systems, typically relying on commercial avionics packages to provide the hardware and baseline software needed for unmanned vehicle flight testing. This paper desc...

This paper describes a simulation model that has been used for controller design and stability and performance analysis of a micro X-CELL helicopter as central element of the Autonomous Scout Rotorcraft Testbed (ASRT) developed at Georgia Institute of Technology, Atlanta, USA. The general model, simple, yet comprehensive and efficient for the task at hand, consists of the following elements: he...

The unsteady, aerodynamically induced resonance of aircraft structures may lead to potentially destructive vibrations when left unaccounted for in flight control system design. Such aeroelastic modes are difficult to accurately predict analytically, and computational models require calibration, verification, and validation. The successful design of control systems that actively suppress aeroela...

B Abstract. The present paper is an introductory and survey paper of the treatment of realistically modelled optimal control problems from applications in the aerospace eld. Especially those problems are considered which include diierent types of constraints. In the tutorial part of the paper, recipes are given for the treatment of optimal control problems for which, among other constraints, co...
