Servo control technique of gyro stabilized platform for gravimeter
2014
The double-shaft gyro stabilized platform has been used for the gravimeter horizontal stabilization, which can eliminate the swing interference from the rocking base in the sea. Focus on the unknown external disturbances and internal friction disturbance, an ADRC (active disturbance rejection control) control scheme for the servo system has been presented in the paper. The torque compensating model based on the ADRC controller is been built and simulated, and the simulation results show that the controller can compensate the unsuspected interference, and guarantee the control precision of the stabilized platform.
