ln this paper, simultaneous strong stabilization problem is considered, and it is shown that there is no upper bound for the minimal order of a simultaneously strongly stabilizing compensator, in terms of the plant orders, A similar problem was also considered in [11], where it was shown that such a bound does not exist for the strong stabilization problem of a single plant, But the examples given in [11] were forcing an approximate unstable pole-zero cancellation or forcing the distance between two distinct unstable zeros to go to zero. In this paper it is shown that : i) If approximate unstable pole-zero cancellation does not occur, and the distances between distinct unstable zeros are bounded below by a positive constant, then it is possible to find an upper bound for the minimal order of a strongly stabilizing compensator, and ii) for the simultaneous strong stabilization problem (even for the two plant case), such a bound cannot be found.
