The invention relates to a band-type brake power supply control method and device, a band-type brake power supply and an elevator band-type brake system.The band-type brake power supply control method comprises the steps that the output voltage of the band-type brake power supply in each preset period is collected to serve as feedback voltage, and the deviation between each feedback voltage and target voltage is calculated; according to the deviation and a PID control parameter, calculating a PID variable quantity of each preset period, and accumulating the previous PID variable quantities to obtain a PID output signal of the current preset period; the PID control parameters comprise a proportional parameter, an integral parameter and a differential parameter; wherein before the band-type brake power supply is connected to a load, the proportion parameter, the integral parameter and the differential parameter are adjusted to be within a first preset range, and then the differential parameter is controlled to be reduced to be within a second preset range; and adjusting the output voltage to the target voltage according to the PID output signal. The output voltage conversion cost of the band-type brake power supply is reduced, and the output voltage precision of the band-type brake power supply is improved.
