| Abstract: | Considering the dynamic model of wheeled mobile robot with non-holonomic constraint and input saturation,quasi-infinite horizon nonlinear model predictive control of its full dynamic error system was studied.Local stabilization controller and invariant terminal region were obtained by online linearization along the nominal trajectory.Simulation results presented in term of tracking "8-shape" trajectory show better tracking performance with the satisfaction of control input constraints. |

| Keywords: | automatic control technology wheeled mobile robot non-holonomic constraint control constraint nonlinear MPC |
