1. An adaptive control method for a mobile X-ray machine, comprising:
acquiring operating information of a battery, and determining a state of the battery;
selecting a first control value if it is determined that the battery is in a failure state;
if it is determined that the battery is not in the failure state, determining whether a residual charge of the battery is less than a low charge threshold; if the residual charge of the battery is less than the low charge threshold, determining that the battery is in a low charge state, and selecting a second control value; if the residual charge of the battery is not less than the low charge threshold, determining that the battery is in a normal state, and selecting a third control value; and
acquiring circuit parameter information of a capacitor charger, controlling the capacitor charger based on the circuit parameter information and the first control value when the battery in the failure state, and controlling the capacitor charger based on the circuit parameter information and the second control value or the third control value when the battery is not in the failure state;
wherein the circuit parameter information comprises an input power, an output power, an input voltage, an input current and an output current of the capacitor charger,
wherein, if the battery is in the failure state, setting the first control value as a first output power reference value or a first input voltage reference value or a first input current reference value, and obtaining a difference value according to the circuit parameter information and a corresponding reference value, and obtaining a state operation signal based on the difference value according to a preset control algorithm to control the capacitor charger.
