    Abstract: To address the output voltage stability issue of DC/DC converters with constant power load, a composite preset performance control strategy is proposed to stabilize the output voltage of DC/DC converters. By employing precise feedback linearization techniques, the nonlinear uncertain DC converter system is transformed into the brunovsky standard form. A nonlinear disturbance observer estimates unknown disturbances, while feedforward compensation enhances output voltage regulation accuracy, effectively addressing system uncertainties and external disturbances. A preset performance controller is designed based on the backstepping method to ensure the output voltage tracking error remains within a preset range. Building upon backstepping method, a composite nonlinear controller integrating adaptive control and preset performance is constructed. Simulation results validate the effectiveness of this strategy.
    Key words: DC converter; adaptive control; preset performance control; backstepping method; parameter disturbance
