A useful performance management technique for such Accepted 5 September 2011 software systems is the relative guarantee feedback control scheme. The existing approaches for this Available online 20 October 2011 class of control systems are mainly based on off-line linear or on-line model identification and control Keywords: techniques, which tend to have performance issues in the presence of nonlinearities induced by this Nonlinear modeling scheme. Instead of using such modeling techniques, this paper proposes a new approach for QoS Block structure Hammerstein–Wiener performance management and resource provisioning by using an off-line identification of Hammerstein model and Wiener nonlinear block s
