ABSTRACT:
A method of suppressing resonances in electro-mechanical servo systems is disclosed. The servo systems are of the type where first signals indicative of actual position of the servo system are differentiated and second signals indicative of the acceleration of the system are integrated. The differentiated signals are applied to the integrator in order to provide accurate initialization thereof. In modes of operation where the acceleration of the system is substantially zero, the differentiators are not used, thus decoupling the mechanical system from the electronic control system and eliminating resonance from the servo loop. The duty cycle of the differentiators is varied in differing modes of operation of the servo system so as to provide maximum bandwidth and speed to the system coupled with minimum errors in positioning. The system is described in connection with the servoing of magnetic read/write heads radially with respect to rotating magnetic disk data storage media.
