Abstract:
In accordance with the present disclosure, a method for controlling an anti-vibration actuator is provided such that the position of the applied opposite rotation in a gyro stabilization process can be measured using capacitance sensing. In some embodiments, a rotor plate attached to a rotor and a stator plate attached to a stator can be used to create a capacitance. When the rotor moves, a distance change value of the rotor can be calculated based on the capacitance measured between the rotor plate and the stator plate. In these embodiments, the cost and the form factor of the aforementioned anti-vibration actuator are reduced compared to implementation of magnetic field sensors in the anti-vibration actuator.
