Backstepping controller with force estimator applied for mobile robot

In this paper, we present the concept of nonlinear control technique for trajectory tracking problem of mobile robot type unicycle. the design of the proposed controller is combines a backstepping controller and the force estimator method. The main aim of this study is to design a robust control law in the presence of disturbances using the backstepping with estimation of the forces. The approach consists to estimate the perturbation using an adaptive controller, the effectiveness of the proposed approach is demonstrated through simulation and experimental results.
