In this paper we formulate and solve optimal control problems for power generating kite systems. Here, the kite generates energy by periodically pulling a generator on the ground while flying fast in a crosswind direction. We are searching for an intrinsically open-loop stable trajectory such that the kite generates as much power as possible without needing feedback, while neither the kite nor the...
This paper presents a robust adaptive algorithm with smooth sliding mode for bilateral control system which necessary uses for achieving in teleoperation. The system uses a hybrid structure to implement simultaneous force and position control, with a two-channel controller. The desired trajectory is the position of a master device manipulated by a human operator, which serves as the reference position...
This paper proposes extensions to a recent control Liapunov function (CLF) based method for designing dynamical systems with trajectories that converge to the zeros of a nonlinear vector function f . Specifically, the CLF design method is extended to the case when the Jacobian of the vector function can be decomposed into a known part and a partially known part, for which certain norm bounds are known...
A mobile manipulator service robot comprising a mobile platform with a three-link arm mounted on top of the platform is considered. A torque compensation control approach is proposed for the robust motion control of the robot. Considering the coupling disturbance between the platform and the manipulator, the nominal model of service robot is built, applying computed torque and proportion-differential...
Poincare-like-alter-cell-to-cell mapping method is proposed to search for the tracking target point, when the slope of the ground or the structure parameters of the underactuated biped robots have changed. The finite-time robust trajectory tracking control strategy is designed to make the states of the system reach the tracking target point in finite time. This control strategy is based on the theory...
