The problem is reduced to the pole assignment problem by a state feedback (modal control) in a descriptor system or a regular one. It is shown that the zero assignment and pole assignment are mathematically equivalent problems.12 pages, TeX (or Latex,ets)Dynamical SystemsOptimization and Control93Bxxtext
