Considering pitch channel simplified model of missile control system, a VSCL(variable structure control law) is designed by using overload and angle velocity signals. Especially, an analysis is proposed for the situation of equal control with uncertainties. An integral action is introduced to compensate the uncertainties and a soft function is adopted to solve the chattering problem of VSC. Fin...

We present a control scheme that does not require exact knowledge of the model of an underwater vehicle while maintaining robustness against both parameter uncertainties and environment disturbances. An important aspect of the proposed control is the relative simplicity of its implementation. To verify the effectiveness of the controller, we use an efficient simulator that takes into account th...

This paper deals with the stabilization of a rotating body-beam system with torque control. The system we consider is the one studied by Baillieul and Levi in [1]. In [12] it has been proved by Xu and Baillieul that, for any constant angular velocity smaller than a critical one, this system can be stabilized by means of a feedback torque control law if there is damping. We prove that this resul...

This paper introduces a link-type tracked vehicle, which is developed for potential applications such as Ž re Ž ghting, handicapped assistance and mine detection in various hazardous environments. The vehicle consists of three parts — front frame, rear frame and body. The front frame is connected to the rear frame by a rotational passive adaptation mechanism, which is the driving mechanism of t...

The problem of coordinated control of a leader-follower system is solved using a virtual vehicle approach to alleviate information requirements on the leader. The virtual vehicle stabilizes to a shifted reference position/heading defined by the leader, and provides a reference velocity for the synchronization control law of the follower. Only position/heading measurements are available from the...

Abstract: Lidars have gained a lot of popularity in the field of wind energy, partly because of their potential to be used for wind turbine control. By scanning the oncoming wind field, any threats such as gusts can be detected early and high loads can be avoided by taking preventive actions. Unfortunately, lidars suffer from some inherent weaknesses that hinder measuring gusts; e.g., the avera...
