In this paper, we solve the point stabilization of mobile robots via state-space exact feedback linearization. The state-space exact feedback linearization has not been possible in the past for the point stabilization of mobile robots due to the restricted mobility caused by nonholonomic constraints. Under some proposed coordinates, however, the point stabilization problem can be exactly transformed into the problem of controlling a linear time-invariant system. Thus, using well-established linear control theory, the point stabilization of robots can be easily formulated. |
