REDUNDANT CONTROL SYSTEM OF ELECTRO-HYDRAULIC CONTROL VALVE

摘要

The present invention relates to a system for controlling an electrohydraulic valve. The technical objective to be solved is to share an opening degree value through communications between each individual unit module and the opening degree value determined by each individual unit module of a valve opening degree control module, and apply an integral controller capable of minimizing an error with respect to a full range of an opening degree of a valve since each servo module selects the opening degree vale shared by the communications so that the opening degree values recognized by each servo module are the same. Moreover, the purpose of the present invention is to minimize error occurrence by applying a correction value in accordance with the opening degree of the valve to a bias constant when a proportional controller is applied to the inside of each individual unit module of the valve opening degree control module.
