Abstract

목표제어량에 대응한 목표 듀티값에 따라, 복수의 펄스로 구성되는 듀티신호의 각 듀티값을 변조제어함으로써 듀티신호를 결정하는 듀티값의 최소 분해능 그 자체를 바꾸는 일이 없이 액추에이터의 제어 분해능을 실질적으로 리니어로 설정하여 액추에이터의 제어 정밀도를 향상시킨 듀티구동 제어장치를 얻는다.The control resolution of the actuator can be controlled substantially without changing the minimum resolution itself of the duty value for determining the duty signal by modulating each duty value of the duty signal composed of a plurality of pulses in accordance with the target duty value corresponding to the target control amount To obtain a duty drive control device in which the control precision of the actuator is improved.

액추에이터의 목표제어량에 따라 소정의 펄스주기의 듀티신호를 결정하고, 펄스주기마다 액추에이터에 인기함으로써 액추에이터를 목표제어량만큼 구동제어하는 듀티구동 제어장치에 있어서, 제1듀티값(α+1)·δ을 가지는 듀티신호와, 제1듀티값과 다른 제2듀티값 α·δ을 가지는 듀티신호를 목표제어량에 따라 소정수씩 조합하여 생성한다.A duty control unit for determining a duty signal of a predetermined pulse cycle in accordance with a target control amount of the actuator and driving the actuator by a target control amount by being popular in an actuator every pulse period, And a duty signal having a second duty value? 占 different from the first duty value are generated by combining a predetermined number in accordance with the target control amount.
