This contribution presents a parametric approach to the frequency domain design of state feedback controllers in the general case of multiple closed loop poles. By introducing the set of generalized pole directions as design parameters a compact parametric expression is derived for the closed loop denominator matrix parameterizing the state feedback controller in the frequency domain. No assumptions are imposed on the closed loop poles and the pole directions. Connecting relationships are established between the time and frequency domain approach to parametric state feedback design. A simple example demonstrates the proposed design procedure.
