Wall-following control problem for a mobile robot is to move it along a wall at a constant speed and keep a specified distance
to the wall.This paper proposes wall-following controllers based on Lyapunov function candidate for a two-wheeled mobile robot (MR) to
follow an unknown wall. The mobile robot is considered in terms of kinematic model in Cartesian coordinate system. Two wall-following feedback controllers
are designed: full state feedback controller and observer-based controller. To design the former controller, the errors of
distance and orientation of the mobile robot to the wall are defined, and the feedback controller based on Lyapunov function
candidate is designed to guarantee that the errors converge to zero asymptotically. The latter controller is designed based
on Busawon’s observer as only the distance error is measured. Additionally, the simulation and experimental results are included
to illustrate the effectiveness of the proposed controllers. 相似文献

This paper proposes an adaptive controller for partially known system and applies to a two-wheeled Welding Mobile Robot (WMR)
to track a reference welding path at a constant velocity of the welding point. To design the tracking controller, the errors
from WMR to steel wall is defined, and the controller is designed to drive the errors to zero as fast as desired. Additionally,
a scheme of error measurement is implemented on the WMR to meet the need of the controller. In this paper, the system moments
of inertia are considered to be partially unknown parameters which are estimated using update laws in adaptive control scheme.
The simulations and experiments on a welding mobile robot show the effectiveness of the proposed controller. 相似文献

《Mechanism and Machine Theory》1987,22(1):77-83
The algebra of rotations of a vector, a portion of the Theory of Conjugate Surfaces, which includes the algebra for the combination and sequence-reciprocation of two successive rotations, and the algebra for the resolution of a given rotation into three component-rotations, is introduced. Its applications in the kinematical analysis of a nRmP robot and in the derivation of the closed-form solution for conventional 6R and 5R robots, are illustrated. A new concept, the work-attitude of the end-effector of a robot with its base-point being fixed at an assigned point, is proposed, and is discussed for cases of conventional 6R and 5R robots with use of the algebra of rotations. 相似文献

Sliding mode control of two-wheeled welding mobile robot for tracking smooth curved welding path 总被引:1,自引:0,他引:1
In this paper, a nonlinear controller based on sliding mode control is applied to a two-wheeled Welding Mobile Robot (WMR)
to track a smooth curved welding path at a constant velocity of the welding point. The mobile robot is considered in terms
of dynamics model in Cartesian coordinates under the presence of external disturbance, and its parameters are exactly known.
It is assumed that the disturbance satisfies the matching condition with a known boundary. To obtain the controller, the tracking
errors are defined, and the two sliding surfaces are chosen to guarantee that the errors converge to zero asymptotically.
Two cases are to be considered : fixed torch and controllable torch. In addition, a simple way of measuring the errors is
introduced using two potentiometers. The simulation and experiment on a two-wheeled welding mobile robot are provided to show
the effectiveness of the proposed controller. 相似文献
