Bonnard, Bernard (ed.) et al., Analysis of controlled dynamical systems. Proceedings of a conference held in Lyon, France, July 1990. Boston, MA: Birkhäuser. Prog. Syst. Control Theory. 8, 347-357 (1991).
This paper addresses the disturbance decoupling problem via dynamic state feedback for control systems described by nonlinear differential equations. This had been done previously using two different approaches: Differential algebraic methods and the invertibility algorithm. In this paper, a differential geometric approach is followed. The so-called “dynamic controlled invariant distribution” is defined and conditions are given for the existence of the minimal such distribution containing the differentials of the output functions. Moreover, a relation is established between the minimal dynamic controlled invariant distribution containing the differentials of the output functions and the solvability of the dynamic disturbance decoupling problem.
