This paper proposed a novel sensor based backstepping control mthod for hypersonic vehicle with actuator compensator. The novel sensor based backstepping control method will apply the so-called “approximate dynamic inversion” to design the virtual control law for each subsystem, not just for the last subsystem. Compared with the traditional method, it does not need all of the precise aerodynamic parameters...
The problem of robust stabilization of time-delay nonlinear systems with Markovian jump with a triangular structure is studied. Based on backstepping method, we prove that the closed system is almost surely asymptotically stable and the controller and the associated Lyapunov function is independent of the generator of the Markov process.
In this paper, the stability analysis of an hexarotor micro-aerial vehicle for outdoor applications using IMU sensors is presented. The dynamic model of the hexarotor was expressed using the Newton-Euler laws jointly with a full state robust back stepping controller, not only when it is hovering, but also when it is taking-off, or landing, or flying to perform a task. The experimental hexarotor is...
Space exploitation will require efficient techniques for manipulating passive objects on orbit. This work presents a manipulation concept that utilizes both the on-off thrusters and manipulator proportional forces to manipulate passive objects on orbit more efficiently. The system dynamics arising from the unilateral constraints and the on-off thrusting are discussed. The manipulation concept is illustrated...
