Title: Method for controlling synchronous motor
Inventor: SEKIGUCHI TAKASHI
IPC: H02P21/05
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To control a current to the minimum torque ripple with maximum efficiency by finding the control current pattern which can obtain the unique zero torque ripple which is outputted from a three-phase inverter with the distorted induced electromotive force of a permanent-magnet synchronous motor and the minimum copper loss. SOLUTION: In a method for controlling synchronous motor, a control current is made to follow an induced electromotive force vector by defining a three- phase magnetic flux resultant vector angle found from an induced electromotive force as the angle θ of rotational coordinates, but, when the relation among the field ϕ, induced voltage E0, current I, and q-axis vector at a certain moment is indicated, (θ+90 deg.-θe) is the difference between the angles of the q-axis and E0 vector. When the angle difference is not '0', the efficiency of a synchronous motor drops. Therefore, the armature current of the motor can be made to follow the induced electromotive force vector by controlling the current to become Id*=0 when the angle basis of the rotational coordinates are moved from the conventional d-axis to the resultant vector of the magnetic flux density ϕuntil ϕ becomes the d-axis and E0 becomes the q-axis. Therefore, a current can be controlled to the minimum torque ripple with the maximum efficiency.
