Publication number: 20140312809Abstract: An apparatus for controlling a multi-winding rotary machine including an armature formed of a plurality of winding sets. In the apparatus, a command voltage calculator calculates command voltages to be applied to each winding set so as to control currents detected by a current detector to their respectively corresponding command currents. An interfering voltage calculator calculates, for each of the winding sets, interfering voltages proportional to the rotation speed of the rotary machine. An interfering voltage compensator compensates, for each of the winding sets, the command voltages for their respectively corresponding interfering voltages. An operation unit operates a voltage applicator to apply output values of the interfering voltage compensator to each winding set.Type: ApplicationFiled: January 16, 2014Publication date: October 23, 2014Applicant: DENSO CORPORATIONInventors: Jun ISHIDA, Tomoya Takahashi

Patent number: 8847527Abstract: An estimation section calculates estimated currents corresponding to switching modes, which are provisionally set by a mode setting section. A mode determination section determines one of modes, which has a smallest difference between the estimated currents and command currents, to be a final switching mode. A drive section drives an inverter in the switching mode determined by the determination section. The estimation section uses transient-state inductances as coefficients of time differentiation of currents in voltage equations used for estimation of the estimated currents. These are different from steady-state inductances, which are coefficients of multiplication of currents and electric angular velocity.Type: GrantFiled: September 7, 2012Date of Patent: September 30, 2014Assignee: Denso CorporationInventor: Tomoya Takahashi
