OPERATION METHOD OF DEVICE FOR CONTROLLING ELECTRIC ACTUATOR IN OPTIMAL OPERATION CURRENT DISTRIBUTION

摘要

PROBLEM TO BE SOLVED: To provide an operation method of a low cost electric actuator control device.

SOLUTION: A method for operating a device 1 for controlling an electric actuator 3 comprises: a pair of input terminals 4 and 5 connected to electrical energy sources 6 and 10 when the device is in use; multiple pairs of output terminals 7 and 8 connected between each other when each of the electric actuators 3 is in use; switch means 11 and 12 controlled for connecting the electric actuator 3 to the electrical energy sources 6 and 10 independently from each other. The method is composed of a process for controlling the switch means 11 and 12 controlled for supplying a current to the electric actuator 3 via the electrical energy sources 6 and 10. The control process includes: a process in which a specific electric actuator 3 determines the possibility of a series of operation states in which a current is supplied simultaneously from the electrical energy sources 6 and 10; and a process in which a current supplied to the specific electric actuator 3 is phase-shifted temporarily in order to reduce the effective value of the current taken out from the electrical energy sources 6 and 10.
