| Abstract: | The global practical output tracking control problem for a class of nonlinear systems with ISS unmodelled dynamics was studied.The system under investigation has the nonlinearly appearing unknown parameters,unknown nonlinear uncertainties as well as ISS dynamic uncertainty.Unlike the existing works,the sign of the control coefficients are not assumed to be known in the paper.By using the Nussbaum gain technique and the integrator backstepping method,a dynamic partial-state feedback adaptive controller was d... |
