Abstract

Over the last decade, predictive control has emerged as the standard for monovariable and multivariable control systems in the process industries. Its ability to handle complex systems make it an attractive tool for many challenging tasks. In this paper, the design of the nonconstrained and constrained generalized predictive controllers is reviewed and assessed to control the up-link power on a WCDMA system. Simulation results are shown not only to evidence that a replace from bang-bang to predictive technologies can be an efficient manner in power command but also to illustrate that the effects of radio channel loss of the system can be over-compensated.
