The invention relates to a dynamic start-stop control system of a flexible gyroscope on a strapdown vertical reference system, comprising a sampling filtering delay circuit, a comparing amplifying state switch circuit, an analog switch control circuit and a force feedback delay variable-K control circuit. The input end of the sampling filtering delay circuit is connected with the output of a subcontrol torquer of a flexible gyroscope. Shown by sampling, the winding of the subcontrol torquer of the flexible gyroscope generates an induced voltage signal when the rotation speed of a rotor changes; and the induced voltage signal is filtered and amplified to control the amplification factor of a force feedback circuit and further control the static and dynamic start and stop of the flexible gyroscope through the force feedback circuit. Due to the adoption of the dynamic start-stop control system, the precision and the service life of the flexible gyroscope on the strapdown vertical reference system can be improved and prolonged. The dynamic start-stop control system adopts simple electronic circuits, is easy to implement and convenient for parameter adjustment and has the advantages ofstrong interchangeability and the like.
Description
technical field [0001] The invention relates to the field of navigation control, in particular to a dynamic start-stop control system of a flexible gyroscope on a strapdown vertical reference system. Background technique [0002] Flexible gyroscopes are widely used in inertial navigation in the fields of aerospace, ships and ships. In the current flexible gyroscope control system, the flexible gyroscope and the rebalance loop constitute a precise closed-loop gyro control system. The center of the pedestal) keeps the output of the gyro annunciator at a minimum in real time. [0003] When the flexible gyroscope is used in a strapdown inertial navigation system, since the gyroscope shell is directly connected to the carrier, the gyroscope will be in the same motion state as the carrier. When the navigation device is started in a dynamic state, The large current impact of the initial maximum signal of the gyroscope on the main control torque winding of the gyroscope may caus...
