A method for suppression of undesirable according to the barrel expensive signals for the running time, a relatively deviations between an input arrangement and a according to the barrel a system in a control circuit

摘要

A device is presented which suppresses unwanted feedback signals. It decreases oscillations in a control loop. The signals form as a result of delays in relative motion between a movable controlled element and a feedback system including a detector for conversion of movement into electrical signals. The signals are used to control the element position. Compensation signals for each ordinate controller of the system are separately generated by a network (19) with duration corresponding to the mechanical delay time when the control signal reaches a sufficiently high level to operate the final control element. The new and previous compensation signals are summed and used to reduce the associated measurement signal.
