US 2014/0156089 A1 · DEVICE AND METHOD FOR CONTROLLING A FLUID ACTUATOR

Abstract

A hydraulic actuator control system for controlling the motion of a master actuator and at least one slave actuator may include an external supervisory computer for sending command signals. A hydraulic control system may be connected to the master actuator and the supervisory computer. The hydraulic control system may include a microprocessor and a master hydraulic control valve for controlling the flow of a pressurized fluid to the master actuator based on the command signals. The hydraulic actuator control system may include at least one slave actuator having at least one slave sensor connected to the microprocessor and having at least one slave control valve for controlling the flow of pressurized fluid to the slave actuator. The slave control valve and the slave sensor may be controlled by the microprocessor.
