Comparative Application of Model Predictive Control Strategies to a Wheeled Mobile Robot

Hoai Nam Huynh, Olivier Verlinden, Alain Vande Wouwer
2017 Journal of Intelligent and Robotic Systems  
This paper reports on the application of predictive control strategies to a wheeled mobile robot.  ...  All three control strategies offer satisfactory reference tracking but MPC allows a reduction of the energy consumption of up to 70 % as a result of setpoint anticipation.  ...  In this study, using a T-filter would not be useful as the wheeled mobile robot moved on a smooth surface and an integrator was already embedded into the control law to reject disturbance.  ...

2010 2010 IEEE/RSJ International Conference on Intelligent Robots and Systems  
Finally, we show that this system provides highfidelity odometry estimates and is able to compensate for wheel slip on a four-wheeled omnidirectional mobile robot base.  ...  However, slipping of the Mecanum wheels results in poor dead-reckoning estimates from wheel encoders, limiting the accuracy and overall utility of this type of base.  ...  The robot was given 20 seconds for each edge or waypoint since this was determined to be larger than the 95 percent rise time for both controllers even in the presence of actuator saturation.  ...
