This paper presents prediction maximum power point tracking (PMPPT) controller for PV-battery micro-satellite systems with body mounted Solar Panels. The proposed PMPPT method includes conventional perturbation and observation (P&O) MPPT method and grey prediction method to improve the efficacy of PV system with auto-tuning the perturbation step. This paper uses the Taiwan Universities United Simulation (TUUSIM) software to simulate the PV output power and power budget of the designed TUUSAT_1B micro-satellite. From the simulated and experimental results, we can see that the accuracy and MPPT speed of proposed PMPPT method are better than the conventional MPPT method for regular orbit of the micro-satellite.
