| Abstract: | A problem of output tracking for a class of timevarying nonlinear control systems is studied in this paper.Firstly,the definitions of timevarying Lie derivatives and relative orders for timevarying nonlinear systems are presented.Then,state feedback control laws are proposed using the inputoutput feedback linearization techniques.which can make the outputs of closedloop systems asymptotically track the desired signals.Finally,a numerical example is given to illustrate the effectiveness of the designed method and controllers. |
