Summary: | The invention discloses a self-tuning method for control parameters of a low-ripple adjustable direct-current stabilized power supply. The method comprises the following steps: establishing a mathematical model between control parameters K1, K2, K3 and K4 of proportional integral-vector proportional integral compound control and an output voltage ripple coefficient alpha and steady-state precision beta of the stabilized power supply; optimizing each control parameter of proportional integral-vector proportional integral compound control by adopting a multi-target artificial bee bird optimization algorithm so as to obtain a function relational expression between the optimal value of each control parameter and the actual output current Io of the voltage-stabilized power supply; therefore, corresponding optimal control parameters under different currents can be obtained, so that the direct-current stabilized power supply can obtain the optimal output voltage ripple coefficient and the optimal steady-state precis |
