Predictive Control Using Fuzzy Models Applied to a

Fuzzy control systems and predictive control techniques has been widely accepted for industrial applications. Fuzzy modeling has received particular attention with in the industry and the nance sectors due to the qualitative insight about the behaviour of the modeled process. Predictive control had been focused on linear systems and time variant linear systems (Adaptive Predictive Control). These adaptive techniques demand slow changes on the parameters to achieve a good performance. This situation generates the necessity of Predictive Control Techniques based on Non-linear Models. This paper presents an algorithm for multivariable predictive control using fuzzy models. The algorithm converts the non-linear program needed to solve the optimal control problem for nonlinear plants, into a quadratic program with a fast solution. The eeectiveness of the algorithm is de-mostrated by a simulation of a steam generating unit used for electricity generation.
