Abstract:
For a class of stochastic state-feedback systems, the state-variance upper-bound index consistent w ith pre-specif ied circular-pole index is discussed via linear mat rix inequality ( LMI) approach, a good range is given for variance upper-bound index consistent w ith prespecif ied pole index. The opt imizat ion of H-infinite at tenuat ion index from disturbance input to cont rolled output is studied for the considered systems under const raint s of consistent pole index and variance upper-bound index . A sub-opt imal value of H-infinite index is obtained via LMI approach and a method to find the const rained sub-opt imal cont rol is provided. Finally, the obtained results are illust rated by a numerical example.
