摘要： An actuation system is proposed for an optical system, comprising a voice coil motor for actuating the optical system, the voice coil motor comprising a magnet and an electric coil, a position measuring unit for measuring the position of the electric coil and providing a position feedback signal, and a control unit for closed loop control of the position of the optical system based on a target position and the position feedback signal, used for generating a drive signal for the electric coil. According to the disclosure, a ferromagnetic element is arranged in proximity to the electric coil so that the inductance of the electric coil depends on its position. Further, the position-measuring unit measures the inductance of the electric coil and determines the position of the electric coil based on the determined inductance.

摘要： A method of estimating inductances and flux linkages of an electrical machine supplied with drive currents via current regulators. Drive current values are measured and fed back to the regulators for closed-loop control. The method includes providing one current regulator with an alternating current value either for a direct axis current reference i*d or for a quadrature axis current reference i*q of the machine current vector, while providing another current regulator with a predetermined direct current value for the remaining one of the two current references i*d and i*q. After a predetermined time, a varying signal is superimposed onto an output signal generated by the current regulator in response to the AC value. Finally, a contribution signal, which corresponds to the contribution of the superimposed varying signal to the drive currents, is determined, and the machine inductances and flux linkages are estimated on the basis of the contribution signal.

摘要： Determination of an estimated initial angular position of the rotor of an AC motor includes application of voltages corresponding to a high frequency reference signal vector to the stator windings of the motor and production of an estimated initial angular position of the rotor as a function of the resulting q-axis stator current component iq_HF, adjustment of transformation of signal vectors from stationary to rotating coordinates and vice versa using the estimated angular position and production of an adjusted estimated angular position of the rotor as a function of the q-axis stator current component as adjusted. Determination of an initial estimated angular position of the rotor and production of an adjusted initial estimated angular position of the rotor is performed with the rotor at standstill and before initially applying voltage corresponding to the drive signal vector to the stator windings, and production of an initial value of a drive signal vector command in stationary coordinates uses the adjusted estimated angular position. Determination of an estimated angular position of the rotor after application of stator current may use a different method, such as a physical relative position sensor.

摘要： A motor control device includes an estimator for estimating a rotor position of a motor having a salient pole by using a value corresponding to a q-axis inductance of the motor as an operation parameter where an estimated axes for the control corresponding to d-q axes are γ-δ axes, and a controller for controlling the motor based on the estimated rotor position. The estimator generates a deviation between a d-axis and a γ-axis by performing the estimation of the rotor position based on a value between a real q-axis inductance and a real d-axis inductance of the motor adopted as the operation parameter. The controller controls the motor so that a γ-axis component of a motor current supplied to the motor is maintained to be a predetermined value of zero or close to zero regardless of a value of a δ-axis component of the motor current.
