This paper consist of three parts, in the first part a mathematical model is introduced for the hydrodynamic gas-supported free-rotor gyro. The next part discussed some constraint condition for design torque-rebalance pulse width modulated servo system. The last part present the analysis of coupling effect and decoupling design on the torque rebalance loop. Since exist the trailing torque and anti-spring torque for hydrodynamic gas-supported free-rotor gyro with variable clearance torque device, so that the model different from normal model of general gyro. Therefore the design of the torque rebalance loop also different from general loop. When this gyro used as angle sensor the coupling between one loop and another is important. This paper present a simple method for deeoupling design.
