HYBRID SLIDING MODE CONTROLLER WITH FUZZY COMPENSATION IN THE SLIDING SURFACE

A new form of a sliding mode controller is presented to deal with pH control. It is based on a combination of Sliding Mode Control and Fuzzy Logic. The conventional sliding surface (calculated from an FOPDT model) is modified using a set of fuzzy rules, which are similar to that of a Fuzzy Logic Controller (FLC). This confers to the controller robustness and flexibility to deal with the highly nonlinear behavior found in a neutralization reactor. The new controller performance is compared with a conventional sliding mode controller and PID. Copyright © 2002 IFAC
