Method and system for high temperature protection control of reaction flywheel
By setting a temperature sensor and controller in the reaction flywheel, the temperature protection mode is realized and the output torque is reduced to avoid high-temperature damage. The problem of shortening the motor life of the reaction flywheel in the high-temperature overheating state is solved, ensuring the normal operation of the reaction flywheel.

Abstract
The present invention discloses a method and system for high temperature protection control of a reaction flywheel, which can ensure that the reaction flywheel will not be damaged by high temperature. The method includes: (1) the reaction flywheel runs at a specified torque T0; (2) the controller sets the temperature protection point temperature t0 and the stop output torque temperature t1; (3) the temperature sensor measures the internal temperature t of the reaction flywheel according to the detection cycle; (4) if t0<t<t1, execute step (5); if t1<t, execute step (6); (5) enter the temperature protection mode, in which the reaction flywheel reduces the output torque T to run, and the output torque T decreases with the increase of the internal temperature t, and jumps to step (7); (6) the reaction flywheel runs in a steady state, the output torque T is 0, and the output torque is stopped; (7) the controller performs PI control and outputs a control signal; (8) the motor runs according to the control signal to complete the output torque control.
