Finite Horizon Robust Nonlinear Model Predictive Control for Wheeled Mobile Robots

Abstract: The control of mobile robotic systems with input constraints is still a remarkable problem for many applications. This paper studies the model predictive control-based kinematic control scheme after implementing the decoupling technique of wheeled mobile robots (WMRs). This method enables us to obtain the easier optimization problem with fixed initial state. The finite horizon in cost function of model predictive control (MPC) algorithm requires the appropriate terminal controller as well as the equivalent ter… Show more

“…The advent of recently developed open-source optimisation toolkits [14] - [16], coupled with the enhanced processing capabilities of modern computers, has facilitated the rapid implementation of NMPC for real-time applications. Various NMPC schemes have been proposed to address both control problems using a singular NMPC approach, as detailed in [17] - [19]. These studies typically assume detailed knowledge of the robot's dynamic model.…”

“…In general, MPCs require a system model for predicting the state of the system over a finite horizon Dao et al (2021). This imposes that the system to be controlled and its dynamic model must be known prior to control.…”

“…However, finite-time control, which enables the controlled system to reach the desired trajectory in a finite time, achieves lower costs and superior efficiency. In addition to faster convergence speed, finite-time control generally achieves higher accuracy, better interference immunity, and robustness in closed-loop systems, which has been established both theoretically [33,34] and experimentally [35]. Due to the various advantages of finite-time control, the finite-time control technique is employed in this study to improve the tracking performance of WMRSs, while making the controller design more stringent.…”
