Many techniques of online self-tuning for controller parameters have been presented in several studies [12-15]. This paper presents a new technique for online self-tuning of a Fractional Order PID (FOPID) controller based on both a type1-Fuzzy and a Takaji-Sugeno Fuzzy and deployed to control the horizontal motion of a dual-axis photo voltaic sun-tracker. A modification based on Takaji-Sureno Fuzzy (TS-Fuzzy) has been applied on the Simulink Fractional Order PID block "nipid" from the toolbox of "ninteger" to become suitable for the purpose of the online self-tuning. Several experiments have been carried out on a system model under the control of the modified FOPID block and the results came very satisfactory.
