摘要

A control method based on a single-power caching mechanism. The single-power caching mechanism comprises an active coiling block (11), a driving motor (10), passive coiling blocks (4, 8), and a tape coiling (2). The active coiling block (11) is disposed on the driving motor (10). The active roiling block (11) and the passive coiling blocks (4, 8) are connected through the tape coiling (2). The control method comprises the following steps: 1) when the driving motor (10) needs to be shut down, detecting a rotational inertia I 1 of the active coiling block (11), a semidiameter R of the active coiling block (11), a semidiameter r of the passive coiling blocks (4, 8), and a rotational inertia I 2 of the passive coiling blocks (4, 8); and 2) controlling a breaking torque of the driving motor to be M 1 ‰¤I 1 ×r×M 2 /(I 2 ×R), M 2 being a torsional moment of the passive coiling blocks. Also disclosed is a control system based on a single-power caching mechanism. When the breaking torque M 1 of the driving motor is controlled to be smaller than or equal to I 1 ×r×M 2 /(I 2 ×R), it can be ensured that the active coiling block and the passive coiling blocks remain a same operation state in a process of reducing the speed until they are static completely, rotational distances are equal and the tape coiling is straightened.
