<P>PROBLEM TO BE SOLVED: To provide a control parameter sensitivity analysis device for an electric motor controlling device and a control parameter setting method for the electric motor controlling device, capable of predicting a phase margin or a gain margin that is a target frequency characteristic by setting condition of a control parameter. <P>SOLUTION: The electric motor controlling device comprises: a detection means 2 detecting an operation amount of a detected body comprising an electric motor 1 or a machine 5; an instruction device 4 generating an instruction signal; and a controller 3 receiving the instruction signal and driving the electric motor 1. The electric motor controlling device also has: an open loop frequency response characteristic measurement means 6 measuring an open loop frequency response characteristic not including a characteristic of the controller 3; a controller model 23 of the controller of the electric motor controlling device; an arithmetic means 7 calculating a one-circulation open loop frequency response characteristic from the controller model and the measured open loop frequency response characteristic; and a sensitivity analysis device 12 sensitivity-analyzing relation between the control parameter of the controller and a change of the one-circulation open loop frequency response characteristic. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
