Title:
DRIVE CONTROL DEVICE FOR ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2021/040035
Kind Code:
A1
Abstract:
A drive control device (50) is provided with: a drive position estimation unit (52) that calculates the drive positions of actuators (13, 14, 21-24) applied to an internal combustion engine (20), and acquires, on the basis of motion characteristics of the actuators, estimated drive positions that are estimates of the drive positions of the actuators and that precede true drive positions which are the drive positions of the actuators in reality, by a drive delay time of the actuators; and a drive position prediction unit (53) that calculates predicted drive positions which are the drive positions of the actuators and which precede the estimated drive positions by performing a prediction calculation process at a prescribed calculation cycle while setting the true drive positions or the estimated drive positions of the actuators as initial positions.
