Title: Control apparatus for electric rotating machine
Inventor: IMURA TERUHIRO
IPC: H02P21/18
Filed: 2010-03-18
Abstract: PROBLEM TO BE SOLVED: To solve the problem: the number of times of switching the switched state increases owing to model prediction control.SOLUTION: A voltage vector V(n) expressing a present operation state is temporarily set at a subsequent operation state (step S10), and it is determined whether a norm |edq| of an error vector edq between a prediction current vector Idqe and a command current vector Idqr is equal to or smaller than a threshold value eth (step S18). If it is equal to or smaller than the threshold value eth, it is determined whether a magnitude relation between a norm |Idqe| of the prediction current vector Idqe and a norm |Idqr| of the command current vector Idqr inverts (step S20). When negative determination is made in the step S18 or positive determination is made in the step S20, a change of a voltage vector V(n+1) is considered (step S22).
