Auto-disturbance rejection for NASA solar power generation

To solve this problem, this paper designs a maximum power point tracking system based on booster circuit, and adopts fuzzy auto-disturbance rejection control to improve the conductance increment method with variable step length. . ermal resistance curve as a function of the air flow rate. 5 acc the DC motor angular speed powered by photovoltaic um power point in order to maximize conve ation has uncertainties such as randomness and volatility. Based on the relationship between the rate of conductance change and. . meters is very complicated due to its reliance on the human experi-ences. Therefore, a radial basis function neural network (RBF N) is introduced to regularize the ADRC parameters automatically o a new nonlinear controller with-out depending on the model of the plant.
