HYDRAULIC ACTUATOR CONTROL DEVICE AND HYDRAULIC ACTUATOR CONTROL METHOD |
摘要 |
In a hydraulic actuator control device, a changing tendency of responsiveness of a hydraulic actuator to changes in the oil control valve (OCV) drive duty of a virtual OCV is stored as model control characteristics. The ratio of an actual OCV dead zone width to a virtual OCV dead zone width is calculated as an OCV variation correction coefficient. A basic control amount is calculated based on a deviation between an operating amount and a target operating amount of the hydraulic actuator. An actual OCV in-dead-zone control amount is obtained by correcting a virtual OCV in-dead-zone control amount with the OCV variation correction coefficient, and an actual OCV out-of-dead-zone control amount is calculated based on a virtual OCV out-of-dead-zone control amount. The actual OCV control amount is the sum of the actual OCV in-dead-zone control amount and the actual OCV out-of-dead-zone control amount.
