Title: Controller of rotary machine
Inventor: MIYAJI JUNJI
IPC: H02P27/06
Filed: 2011-06-08
Abstract: PROBLEM TO BE SOLVED: To solve a problem in which, if torque is estimated based on a map which assumes a torque formula "φ*id+P(Ld-Lq)*id*iq" or a specific value for an armature interlinkage flux constant φ, estimation accuracy of torque is largely reduced, because an armature interlinkage flux constant φ varies in such a case where an error, in which magnetic force of a permanent magnet of a motor generator is reduced, occurs.SOLUTION: At a diagnostic torque estimation section 56, diagnostic estimated torque Tde is calculated by dividing effective power EP (=Vn*Ia*cosΔ) with electric angular velocity ω. Here, a norm Vn is a norm of a vector of output voltage of an inverter INV, a norm Ia is a norm of a vector of actual currents id and iq, and a phase difference Δ is a phase difference between a current vector and a voltage vector. At an FB arithmetic system error diagnosing section 60, the presence or absence of an error of an arithmetic system is diagnosed by comparing controlling estimated torque Te and diagnostic estimated torque Tde, which are estimated by a method equivalent to the above formula.
