  • Electrically-powered actuator driving control apparatus and driving control method and vehicle having electrically-powered actuator driving control apparatus
    Patent number: 8447468
    Abstract: It is a task of the invention to obtain a favorable thrust force characteristic with respect to a stroke of an actuator even if the actuator is used in a thrust force control. To solve the task, in the present invention, a linear motor type electrically-powered actuator AC with a linear motor 3 as a drive section is drivingly controlled. With a basic thrust force variation with respect to the stroke in a non-excitation state as a basis, a thrust force command Fc is used to correct a phase of the basic thrust force variation and a magnitude thereof to determine a compensation quantity which corresponds to the thrust force variation with respect to the stroke.
