The invention discloses a capacitive energy conversion type reaction flywheel braking method, which belongs to the technical field of electromechanical control. The technical problems of high heat generation and insufficient energy utilization in the prior art during the deceleration process of the reaction flywheel are solved. The reaction flywheel braking method includes the following steps: under the action of the flywheel drive control circuit, when the reaction flywheel brakes and the PWM is turned off, the pumped voltage generated by the flywheel motor is stored in the electrolytic capacitor, and when the voltage of the electrolytic capacitor is greater than When the power supply voltage of the small satellite power supply is low, the power supply of the small satellite power supply is cut off through the diode; when the reaction flywheel is braking and the PWM is on, the electric energy stored in the electrolytic capacitor is released to the flywheel motor winding to realize the braking of the flywheel. The method converts the mechanical energy of the reaction flywheel itself into electric energy stored in the electrolytic capacitor, and then converts the electric energy into braking force to realize the braking of the flywheel and improve the energy utilization rate of the small satellite at the same time.
Description
technical field [0001] The invention belongs to the technical field of electromechanical control, and in particular relates to a capacitive energy conversion type reaction flywheel braking method. Background technique [0002] In the engineering practice of the reaction flywheel, in the adjustment process of the reaction flywheel, it is often encountered that the reaction flywheel is reduced from a high speed to a low speed to brake the reaction flywheel. At present, the commonly used adjustment method of the reaction flywheel during the deceleration process is mainly to use the method of converting mechanical energy into heat energy by the energy consumption resistor to decelerate the reaction flywheel. This method will generate a lot of heat, and at the same time, it does not make full use of the mechanical energy stored in the flywheel. In the application of small satellites, energy utilization is a more priority design factor. Therefore, the above-mentioned technology c...
