Finally, The jerks and the jumps of torque of each
joint are decreased after optimization, and in consequence,
when each joint of the manipulator is
forced along the optimal trajectories the vibrations
of the pitch and roll angles are reduced as shown in
Figure 18. These results reveal the effectiveness of the
presented PSO with chaos method to solve the contradictory
problem between high operating efficiency
and low residual vibration using limited control
energy.
5. Conclusions
In this paper, the authors investigated two problems of
vibration reduction of wheeled mobile manipulator
with suspension system. To overcome the first problem,
