DESIGN A GAIN SCHEDULED FUZZY CONTROLLER FOR DISTRIBUTED PARABOLIC SOLAR COLLECTORS.

The subject of this article is the gain scheduled fuzzy control for the field of distributed parabolic solar collectors. System modeling has been done in different operation points. These different operation points are caused by various conditions occured by the nonlinear and time-varying behavior of the system based on the different operating points that are considered due to the presence of various disturbances and inputs, the switching mechanism between controllers is performed by a time-controlled structure, which will reduce the effects of disturbances on the system response. The PID controller is then designed based on the Anti-Windup circuit and a feedforward controller that runs parallel to it. The use of a feedforward controller can also improve the system response time and its overshoot value, as well as reduce the effect of disturbances on the system. [ABSTRACT FROM AUTHOR]
