摘要：
The locking force of an electromagnetic joystick lock with flux having a flux canceling driver circuit is controlled in order to maintain the control lever of a joystick in a desired position. In one embodiment, the locking force may be in either an activated or deactivated state, and one of a forward or reverse current is applied to the coils of the lock in response to the state, in order to eliminate the residual magnetism when the locking force is deactivated.
