Pole assignment is a well-known method for controller design. If the plant parameter vector is characterized by some uncertainty and if there is some flexibility in the desired closed-Ioop pole vector, the problem of finding a robust controller arises. The solution of this problem is not a simple one of solving linear algebraic equations as in the case of plants given in companion form. The problem is of higher complexity and requires an iterative algorithm, e.g., following a steepest descent method.
