The invention relates to a control apparatus of an electric power steering apparatus structured such as to apply a steering assist force generated by a n-phase motor to a steering system of a vehicle, the control apparatus is provided with at least (n−1) numbers of current detecting means for detecting a current Im in each of phases of the motor, a current command value calculating means for outputting a current command value Imref in each of the phases, and n numbers of current control means, and the control apparatus executes a current control of each of the phases by the current control means having the current command value Imref in each of the phases and the current Im in each of the phases as an input.
A control apparatus of an electric power steering apparatus structured such as to apply a steering assist force generated by a n-phase (in this case, “n” being an integral number equal to or more than 3) motor to a steering system of a vehicle, wherein the control apparatus comprises at least (n−1) numbers of current detecting means for detecting a current Im (in this case, “m” being 1, 2, . . . , n) in each of phases of said motor, a current command value calculating means for outputting a current command value Imref (in this case, “m” being 1, 2, . . . , n) in each of the phases, and n numbers of current control means, and the control apparatus executes a current control of each of the phases by said current control means having said current command value Imref in each of the phases and said current Im in each of the phases as an input.
A control apparatus of an electric power steering apparatus structured such as to apply a steering assist force generated by a three-phase motor to a steering system of a vehicle, wherein the control apparatus comprises three respective-phase back EMF calculating means for calculating back EMFs e1, e2 and e3 in respective phases of said three-phase motor, and two respective-phase current control means, and the control apparatus calculates a command value ref3 in one remaining phase from command values ref1 and ref2 corresponding to outputs of said two current control means, and adds said back EMFs e1, e2 and e3 to said command values ref1, ref2 and ref3.
A control apparatus of an electric power steering apparatus comprising:
