Abstract :
A novel flywheel reaction torque measurement system is proposed to measure the output torque of flywheels. The system structure and principle of the measurement system are presented. Finite-element method is applied to compute the magnetic field and characteristics of the measurement system. An improved disturbance observer is applied in the position closed loop control system. Simulation and experiment show that the system dynamic characteristics can be improved by the disturbance observer.
