$$H^ \infty$$ control with pole assignment in a specified disc. (English) Zbl 0765.93018
Summary: A method of pole assignment in $$H^ \infty$$ control theory is proposed. By this method, all the poles can be placed in a left half-plane or inside a disc on the complex plane and at the same time an $$H^ \infty$$ norm constraint is satisfied. This result can be derived by a bilinear transformation of the complex variable of a transfer function in $$H^ \infty$$ control theory.
