Necessary Conditions for the Removal of Singularities with Dynamic State Feedback

摘要: Abstract This paper examines the possibility of removing singularities from decoupling matrix a nonlinear analytic M.I.M.O. system via dynamic compensation. We show that if given already possesses vector relative degree at each point dense subset state space except singular point, then any feedback yields closed loop mantaining singularity in point. In other words, occurring on boundary set regular points cannot be removed by feedback. order to that, we describe how time derivatives outputs extended are related rows initial system.
