讲座内容:
报告1:In this lecture, the design of different robust controllers is presented to solve the trajectory tracking problem in perturbed unicycle mobile robots. The proposed strategy takes into account the design of two particular sliding variables, which ensure the convergence of the tracking error to the origin despite the effect of some external perturbations (slipping and slippage effects on the wheels). The straightforward structure of the controllers is simple to tune and implement. The stability of the closed-loop tracking error dynamics is demonstrated through a Lyapunov approach. Furthermore, the performance of the proposed approaches is validated through some experiments using a QBot2 unicycle mobile robot.
报告2:In this lecture, the design of a robust controller is presented to solve the trajectory tracking problem in perturbed and constrained unicycle mobile robots. Considering state and input constraints, we provide an interval predictive tracking control for perturbed and constrained unicycle mobile robots. The proposed strategy comprises the design of a robust control law, which is based on an Integral sliding-mode control approach together with an interval predictor-based state-feedback controller through a Model Predictive Control scheme. The robust controller deals with some perturbations in the kinematic model, which represent slipping effects, and with state and input constraints that are related to restrictions on the workspace and saturated actuators, respectively. The performance of the proposed approach is validated through some simulations.
