The great majority of
path following
control laws for either kinematical or dynamical
mobile robot
models are designed assuming ideal actuators, i.e. assuming that any com manded velocity or torque (in the kinematical and dynamical cases respectively) will be instantly implemented regardless of its value. Real actuators are far from being ideal. In particular, only bounded velocities and torques can be realized for any given command. With reference to the kinematical model of a differential drive mobile robot, a known
path following
control law is modified to account for actuator velocity saturation. The proposed solution is experimentally shown to be particularly useful for
high speed
applications where accounting for actuator velocity saturation may have a large influence on performance. In the last few years tremendous progress in
mobile robot
motion control
has been achieved. Typical problems addressed in literature include point stabilization,
trajectory tracking
and
path following
(3) for which either kinematic or dynamic solutions are derived. In real implementations it is important that the controller outputs are bounded to prevent hardware damages. When actuator bounds are not explicitly taken into account during the
control design
phase, a common practical solution is to artificially saturate the actuator inputs (i.e. the controller outputs) to their upper bounds at cost of performance. This paper proposes a
path following
control law that takes actuator velocity bounds explicitly into account. The resulting solution appears to be particularly well suited for
high speed
path following
applications. Given a curve l 2 Rp (where p = 2 or 3) parametrized by some scalar s2 R (by example the curvilinear abscissa), denoting with r2 Rq the pose (position and orientation) of the vehicle being ˙ r = f(r,
