摘要: Host control section 8 is provided with simulation model 8c for simulating the signal transmission characteristics of an electric motor control device. Host control section 8 performs an operation on the actual position command signal θref that is supplied from the host device in accordance with the simulation model, calculates the speed and position of the electric motor corresponding to the actual position command signal θref, and applies this speed and position as first simulation speed signal ωF and first simulation position signal θF, respectively, with each second control sampling period t2. Host control section 8 further generates a linear combination of θref−θF and ωF using, as combination coefficients, constants determined by parameters that characterize the simulation model, and supplies this linear combination as feedforward torque signal TFF for each second control sampling period t2. In this way, the occurrence of error between the actual position signal and the simulation position signal can be prevented even when the control sampling period of the feedforward operation differs from the control sample cycle of the feedback operation.
