We consider the condition of admissibility and the decomposition methods technique of the state space via the spectral properties of the system. Then we apply this approach to a regional exponential stabilization problem using bounded feedback. Applications are presented.enOutput stabilzationSemilinear systemsBounded feedbackArticle681111411222618-6470
