چکیده

This paper considers the problem of output feedback trajectory tracking with a unicycle mobile robot system. A state-feedback controller for the non-linear error dynamics of the robot is combined with an observer that estimates the orientation error based on available trajectory information and measurement of the position coordinates. A stability analysis, derivation and implementation of the resulting controller is given and tested on an experimental mobile robot.

Observer Based Kinematic Tracking Controllers for a Unicycle-type Mobile Robot

In this paper the problem of global trajectory traclcing for the kinematic model of a unicycle-type mobile robot is considered. It is assumed that some of the tracking error coordinates are not measurable. Using a cascaded systems approach we develop full order and reduced order observers, and introduce an observer based controller resulting in IC-exponential convergence of the tracking error. ...

Unstable behavior of a unicycle mobile robot with tracking control

This report considers the unstable behavior which occurs when an orientation-error observer tracking controller combined with a real-time operator-controlled reference trajectory is implemented on an experimental unicycle-type mobile robot. With help of simulations and experiments it is attempted to determine the cause for this behavior. Furthermore, an alternative combined trackinglstabilizing...

Two Observer-based Tracking Algorithms for a Unicycle Mobile Robot

A trajectory tracking problem for the three-dimensional kinematic model of a unicycle-type mobile robot is considered. It is assumed that only two of the tracking error coordinates are measurable. By means of cascaded systems theory we develop observers for each of the error coordinates and show the K-exponential convergence of the tracking error in combined closed-loop observer-controller syst...

Trajectory Tracking for a Group of Unicycle-Type Robots Using an Attitude Observer

The trajectory tracking problem for a group of unicycle-type robots is addressed and solved by means of a partial state feedback strategy based on the leader-followers scheme using an observer to estimate the orientation angle of each mobile robot. The control law is based on an extended kinematic model where the output function to be controlled is the mid-point of the wheels axis of each robot...
