MODELLING AND SIMULATION OF A HYBRID CONTROLLER FOR SOLAR THERMAL GENERATION

In this paper, Parabolic Solar Thermal Generation (PSTG), is studied and analyzed. The optimum control of oil cycle of PSTG is essential in its operation. Improved control techniques of solar thermal generation results to solar energy optimization, so modeling of this system is vital from the control point of view. To control such a complete oil cycle, two controllers are required: 1- a continuous controller to maintain output oil temperature ofthe collectors’ field at a desired level and 2- a switching (discrete) controller to determine active working loop. a combination of continuous and switching controllers are used in thiswork for control system that is: PID switching + Conditional switching. Here after modelling of PSTG, a hybrid control system is suggested and employed in PSTG with real data so the results for different working days are obtained through this method
