Robust Tracking Control for a Class of Nonlinear Systems with L∞_Bouned Disturbance
In the paper, a robust tracking controller is presented for a class of SISO affine nonlinear systems with unknown mismatched uncertainties and external disturbance in input channel.The designed controller has simple structure and concrete expression and include no Lyapunov function. So the proposed controller is easy to compute and complement.The practical stability of output tracking error and the states of the corresponding closed-loop system are demonstrated by Lyapunov stability theorem.Simulation results are presented throughout the paper to complement the theoretical developments.
