Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claim(s) 1-6 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Takatsu (20190260320) cited by Applicant .
Takatsu discloses a motor control device comprising ( claim 1 a motor control apparatus to control motor based on instructed phase indicating a target phase ) , a current control unit configured to control a current by either an open loop control of controlling a current to be supplied to a motor based on a current command value ( see fig 4 constant current controller 517), or a closed loop control of controlling current to be supplied to motor based on current command value and rotational position of rotor of motor ( see fig 4 current controller 503) and rotational position correction unit configured to correct a second phase difference based on a first phase difference ( see fig 8, paragraph 114 further in the present embodiment the command generator 5000 adjusts the instructed phase when motor control method is switched from vector control to constant current control ) the first phase difference being a difference between a rotational position of the rotor in a state where the current control unit controls the current by the closed loop control and a target rotational position of the rotor ( see claim 1 “ a controller including a fist control mode in which motor is controlled by controlling the driving current flowing through the winding of the motor based on a value of a torque current component such that a deviation between instructed phase generated by generator and rotation phase determined by phase determiner is reduced ) the second phase difference being a difference between a rotational position in the closed loop control and rotation position in the open loop control ( see paragraph 114 specifically the command value generator 500b outputs the instructed phase , a phase obtained by adding the phase difference stored in the memory 500c to the instructed phase that is last output) , when the current control unit switches from closed loop control to open loop control ( see paragraph 114 further in the present embodiment the command generator 500 adjusts the instructed phase ref when the motor control method is switched from vector control to constant current control.) Claim 6 Takatsu disclose motor control method for causing a computer to execute acquiring a rotational position of rotor of motor ( see paragraph 75 the phase determiner 513 determines rotation phase of the rotor 4 ), controlling current by either an open loop control of controlling a current to be supplied to motor based on current command value or closed loop control of controlling the current to be supplied to the motor based on the current command value and rotational position ( see fig 4) , and correcting a second phase difference based on a fist phase difference, the first phase difference being a difference between a rotational position of the rotor in a state where the current is controlled by the closed loop control and a rotational position of the rotor in a state where the current is controlled by the open control loop ( see paragraph 114 specifically the command value generator 500b outputs as the instructed phase ref a phase obtained by adding the phase difference stored in the memory 500 c to the instructed phase that is last output) the second phase difference being a difference between rotational position in the closed loop control and rotational position in the open loop control when switching from the closed loop control to the open loop control ( see fig 8 paragraph 114 further in the present embodiment the command generator 500 adjusts the instructed phase when the motor control method is switched from the vector control to the constant current control ) . Claim 2 storage unit for phase difference , see fig 5 memory 500c . Claims 3,4,5 phase difference open loop/closed loop see fig 8 phase jump at tc2 .
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure. Prior art 2007/0040529 discloses in paragraph 67 open and closed loop .
