Abstract: Processes with only one output being controlled by a single newlinemanipulated variable, are classified as Single Input Single Output (SISO) newlinesystems. Many processes,however, do not conform to such a simple control newlineconfiguration. Systems with more than one control loop are known as Multi newlineInput Multi Output (MIMO) or multivariable systems.Most of the controlled newlineprocesses in industries are Multi Input Multi Output processes. The control of newlineMulti Input Multi Output processess is a complicated problem due to the newlinecoupling that exists between the control inputs and outputs. When MIMO newlinesystems are nonlinear and uncertain, their control problem becomes more newlinechallenging and as such there is a need for an efficient tuning method to newlinecontrol both SISO as well as MIMO processes. Fuzzy Logic Controller (FLC) has become an alternative to newlineconventional control algorithms to solve problems dealing with complex newlineprocesses.The main issue in the design of a standard Fuzzy Logic Controller newlineis to well define its parameters so as to maximise the system performance. For newlinethe successful design of FLCs, proper selection of input and output scaling newlinefactors or tuning of other controller parmeters are done through trial and error newlineprocess. Of the various tunable parameters, Scaling Factors (SF) have the newlinehighest priority due to their global effect on control performance. A Fuzzy Logic Controller is said to be adaptive, if any one of its tunable parameters newlinechanges when the controller is in operation. An adaptive FLC that finetunes newlinean already working controller by modifying either its Scaling Factors (SF) or newlineMembership Functions (MF) or both of them is called a Self Tuning Fuzzy newlineLogic Controller (STFLC) . Here, PI type FLCs are used because they newlinecombine the advantages of inherent stability of proportional controller and newlineoffset elimintion by integral controller The performance of PI type Fuzzy newlineLogic Controller can be improved by introducing the self tuning mechanism. newline
