Abstract: This paper considers a finite-time stabilization problem for a class of uncertain nonholonomic mobile robots with dynamic inputs. Using input-state transformation, a three-input chained systems can be obtained. A discontinuous three-step switching controller is presented by applying the theory of finite-time stability and a new switching design algorithm, which can stabilize the closed-loop system to the original equilibrium point in a finite time interval. Simulation results show effectiveness of the proposed approach.
