Asymptotic output tracking of nonlinear differential-algebraic control systems
The problem of asymptotic output tracking is considered for control systems described by a class of nonlinear differential-algebraic equations. Assumptions are introduced, and an algorithm is developed. Based on the algorithm, a nonlinear feedback control law is then constructed which ensures, under appropriate conditions, that the closed-loop system has a unique bounded differentiable solution and the tracking error in the closed-loop system approaches zero when time goes to infinity.
