Abstract :
This paper describes the design of model following control system for nonlinear descriptor system (DS) with disturbances in which the output signals converge to desired signals asymptotically. In this paper, the authors set the nonlinear part (f(ν(t))) of the controlled object as ||f(ν(t))||⩽α+β||ν(t)||γ . (α⩾0.β⩾0.0Sγ<1) and show the boundedness of inner states. In this case, the fact that characteristic roots of the system matrix are stable guarantees the boundedness of inner states. A numerical simulation with disturbances verified the availability of this method
