摘要
This paper considers nonlinear control of a satellite power system. Two different controllers designed for a satellite power system. a first order- sliding mode controller used for maximum power point tracking (MPPT) of the photovoltaic (PV) module and a PID- sliding mode controller used for load voltage regulation as well as charges or discharges battery. The stability of the MPPT unit is guaranteed through Lyapunov stability analysis. The proposed controllers are robust to environmental, load and battery voltage variations. To show the effectiveness of the controllers, a nonlinear satellite power system is chosen as a case study. The simulation results verify the merits of the proposed controller.
