Disturbance rejection problem with stability by static output feedback of linear-time invariant continuous time system is solvable if there is found a static output feedback control law, u(t) = Ky(t) (if possible), such that disturbance q(t) has no influence in controlled output z(t). So, it is needed the necessary and sufficient condition disturbance rejection problem is solvable. By using the definition and characteristics of (A, B)-invariant subspace, and (C, A)-invariant subspace, then it
