METHOD AND APPARATUS FOR AUTOMATIC ADJUSTMENT OF FEEDFORWARD COMPONENT FOR SUPPRESSING REDUNDANT RESPONSE TO STEP ACTION DURING STEPPED TRACKING

摘要

FIELD: radio engineering, communication.;SUBSTANCE: automatic adjustment apparatus 1 is configured to receive an input response signal of a control object 4 in a control system 2 with feedback, in front of which there a FF control unit 5. Stepped response to a stepped target value X is obtained in a state where the FF control unit 5 is turned off, and the degree of redundant response to step action α is calculated from the maximum redundant response to the step action, which corresponds to the maximum stepped response and values of the provided stepped target value. The rising time of the stepped response is calculated from the time beginning from the moment when the stepped target value was provided up to the moment when maximum redundant response to the step action was reached. An instruction is transmitted to the FF control unit 5 to output a multi-step signal S, composed a stepped signal of a first step, which is equal to (1-(α/(1+α))^1/n), multiplied by the input stepped value X, and the next stepped signal, the increment of which is reduced α/(1+α)^1/n times after each expiration of the rising time of the stepped response.;EFFECT: easy implementation and wider field of use.;4 cl, 10 dwg
