A New Improved Perturbation and Observation MPPT Control Algorithm in Photovoltaic System

摘要：

The conventional perturbation and observation (P&O) method is combined by the target tracking technique of data fusion, the adaptive multi-mode MPPT control algorithm is put forward for the first time. The reasonable and long step is selected to insure tracking velocity, the target tracking algorithm is adoptted for weaken and restrain vibration, the target maneuvering detection technique is put to use to judge whether the system is “lose control in fast variation environments, the repeat starting up perturbation and observation (P&O) method in order to strengthen system stability. The experimental result shows the correctness and validity of the method.
