Vietnam Journal of Mathematics 36:4(2008) 473-479 Controllability Radius of Linear System under Structured Perturbations  Nguyen Khoa Son and Do Duc Thuan Abstract.  In this short note, we formulate some new results on robustness measure of controllability of linear systems whose coefficient matrices are subjected to structured pertubations. The notion of controllability radius is introduced and some formulas for its computation are derived. Examples are given to illustrate the obtained results   2000 Mathematics Subject Classification: 06B99, 34D99, 47A10, 47A99, 65P99. Keywords: Linear systems, structured controllability radius, linear multivalued operators.
