| Abstract: | Aiming at the problem that it was difficult to improve the control accuracy and rapid convergence of the ellipse parameters of the vibrating gyroscope under proportional-integral-derivative (PID) control, it was proposed to introduce the discrete-time sliding mode control (DSMC) into the control system of the vibrating gyroscope. This method started from the ellipse parameters that characterize the vibrating gyroscope's working state, and selected the amplitude of the main wave and the amplitude of the quadrature wave as control objects, and then obtained the discrete sliding mode control law. Based on the Simulink model, PID control and DSMC simulation comparison of ellipse parameters are carried out under static (0°/s) and dynamic (100°/s) conditions. The simulation results within 10 s show that the DSMC can reduce the amplitude error of the main wave by 16 LSB and the amplitude error of the quadrature wave by 1 LSB. Under static condition, the angular drift rate is reduced by 0.36 deg/h. And under dynamic condition, the scale factor error is reduced by 5 ppm. The simulation results reflect the robustness and rapid convergence of DSMC. |
