PROBLEM TO BE SOLVED: To provide a drive control method for a reluctance synchronous motor, which is able to achieve both a noise reduction and torque ripple restriction and also ensure followability during high speed rotation.SOLUTION: As a command magnetic flux wave form φwith respect to a magnetic flux wave form generated in each magnetic pole by supply of power to each phase stator coil 7 with respect to an SRM 8, an SRM controller 14 uses a three-time harmonic component that is zero with respect to θ, which is included in an estimation value T(θ) given as a function of electric angle θ, expressed by the formula (5). This reduces torque ripple and noise generated by mechanical deformation of a motor by a harmonic component. By applying a command magnetic flux φas a smooth continuous wave form continuously changing over one period of electric angle, controllability is improved and can be made to follow up to an area where the SRM 8 rotates at a high speed.SELECTED DRAWING: Figure 1 |
