Global Asymptotic Stabilization of a PVTOL Aircraft Model with Delay in the Input
نویسندگان
چکیده
A model of PVTOL aircraft with two delayed inputs is considered. The origin of this system is globally asymptotically and locally exponentially stabilized by bounded control laws. The explicit expressions of the control laws applied are determined through recent extensions of the forwarding approach to systems with a delay in the input. In a second step, the output feedback stabilization problem consisting in globally asymptotically stabilizing the origin of the PVTOL when the variables of velocity are unmeasured is solved through a recent technique which extensively exploits the presence of positive delays in the inputs.

Stabilization of a Pvtol Aircraft with Delay in the Input
In this paper, a model of PVTOL aircraft with two delayed inputs is considered. The origin of this system is globally asymptotically stabilized by state feedbacks determined through recent extensions of the forwarding approach to systems with a delay in the input. In a second step, this result is extended to the case where only the variables of position are supposed to be available by measureme...
متن کاملFinite-time observer-based output-feedback control for the global stabilisation of the PVTOL aircraft with bounded inputs
In this work, an output-feedback scheme for the global stabilization of the PVTOL aircraft with bounded inputs is developed taking into account the positive nature of the thrust. The global stabilization objective is proven to be achieved avoiding input saturation and by exclusively considering the system positions in the feedback. To cope with the lack of velocity measurements, the proposed al...
متن کاملRobust Adaptive Attitude Stabilization of a Fighter Aircraft in the Presence of Input Constraints
The problem of attitude stabilization of a fighter aircraft is investigated in this paper. The practical aspects of a real physical system like existence of external disturbance with unknown upper bound and actuator saturation are considered in the process of controller design of this aircraft. In order to design a robust autopilot in the presence of the actuator saturation, the Composite Nonli...
متن کاملGlobal Stabilization of a Pvtol Aircraft with Bounded Thrust
Global stabilizing control design is proposed for the planar vertical takeoff and landing (PVTOL) aircraft. The methodology is based on the use of nonlinear combinations of saturation functions bounding the thrust input to arbitrary saturation limits. The algorithm is simple and provides global convergence of the state to the origin. K e y w o r d s : Aircraft control, Non-linear control system...
متن کاملStabilization of uncoupled PVTOL aircraft based on a Lyapunov function
In this paper we present a stabilization procedure for PVTOL (planar vertical take off and landing) aircraft with zero coupling coefficient that is defined as the effect of rolling moment on lateral acceleration. A stabilizing control structure has been designed via Lyapunov’s direct method including almost the whole state space and its asymptotic convergence has been proven using La Salle’s in...
