PURPOSE: To obtain a current controller for hybrid permanent magnets whose control design is easy by performing proportional operation following integration on the basis of a voltage equation in a current control part, and besides adding an interference term beforehand. CONSTITUTION: By a magnetic flux current command id*, integration and then proporitonal operation (IP) control are performed. Moreover, a disturbance ωLq iq being an interference term of axis d is added to the system beforehand. A disturbance term is canceled leaving only a first-order lag by subtracting the disturbance ωLq iq from ωLq iq -(Rd +SLd ). Similarly, by a torque current command iq* IP control is performed, and that a disturbance ωLq iq +ω(Mf If +ϕo ) being an interference term of axis q is added to the system beforehand. Also, by a DC field winding current command if*, a disturbance is canceled by adding an interference term PMf Id beforehand along with IP control. As the result of this, in each system a control object becomes a first-order lag system of a time constant determined by the resistance and inductance of the winding, and no disturbance terms are contained, so only to think of response to a command value is enough. |
