OLIVEIRA, José de; TROFINO, Alexandre  and  SOUZA, Carlos E. de. Análise e síntese H_¥ para sistemas LPV. Sba Controle & Automação [online]. 2002, vol.13, n.1, pp. 6-12. ISSN 0103-1759.  http://dx.doi.org/10.1590/S0103-17592002000100003.

This paper deals with the problem of _¥ performance for LPV systems. The _¥ performance index is based on a parameter dependent Lyapunov function with quadratic dependence on the parameters as well as on the system state. This stability notion is appropriate to deal with real parameters with magnitude and rate of change which are confined to a given convex region. Sufficient conditions based on LMI are developed for the _¥ performance analysis of LPV systems and designs of LPV controllers with guaranteed _¥ performance.

Keywords : H_¥performance; LPV systems; LPV control; parameter-dependent Lyapunov functions.
