H/sub /spl infin// control of a flexible transmission system

Abstract

An application of a continuous-time H/sub /spl infin// control to a flexible transmission system is presented. This approach has been proposed in order to assure high control performance in the presence of large load variation on the system. In this approach, the loading variations are considered as the multiplicative perturbation of the nominal plant. The desired specifications are enforced in the H/sub /spl infin// problem as the constraints on weighting functions. To obtain the desired performances, after an initial design procedure, the parameters of weighting functions are tuned and the final weighting functions are derived. The simulation results for three different loadings are given and compared.
