This paper addresses the development of an active fault tolerant control scheme. The methodology is based on a fault detection and diagnosis procedure relying on an unknown input observer designed via Singular Value Decomposition (SVD). Furthermore, the control reconfiguration mechanism is removed in favor of an additional control law directly injected into the nominal one to compensate for the effect...
In this paper, the design process of two robust H∞ control architectures for a Gun Launched Micro Aerial Vehicle — GLMAV — is presented. The process starts with the developement of a nonlinear dynamic model reflecting the important elements of the GLMAV. This model is then linearized around hover and used for the design of static output feedback H∞ controllers for position and orientation control...
This paper considers the problem of controlling the position and the orientation of a Gun Launched Micro Aerial Vehicle - GLMAV - despite unknown aerodynamic efforts. The proposed approach overcomes the problem of gyroscopic coupling by taking advantage from the structure of the thrust mechanism, which is made of two counter rotating propellers. An adaptive linearizing controller is designed, allowing...
This paper considers the question of obtaining a nonlinear trajectory tracking control law for a comprehensive design of a Gun Launched Micro Aerial Vehicle (GLMAV) despite unknown aerodynamic efforts. To this purpose, a nonlinear mathematical model of the GLMAV is firstly presented for hover and near hover flight conditions. Then, an approximate backstepping control law is derived, allowing the trajectory...
