摘要：

The output characteristic of a photovoltaic array is nonlinear and changes with solar irradiation and cell's temperature. The Maximum Power Point Tracking (MPPT) technique is needed to maximize the produced energy. Most MPPT techniques contain the time derivative of the current and the voltage. These electric signals are disturbed by the high frequency noises such as the switching noises of the power device. The low-pass filter is employed to reduce the noises of the circuit. However, the estimation error occurs in calculating the maximum power point. Thus, we apply the adaptive observer to estimate the time derivative of noisy signals. Moreover, we improve the incremental conductance method by using the adaptive observer.
