VACUUM INSULATION MATERIAL, AND MANUFACTURING METHOD FOR SAME
For the purpose of obtaining a micro-step driving control apparatus for a stepping motor in which torque fluctuations caused by the influence of detent torque can be reduced without performing preliminary driving, the apparatus is comprised of a phase difference estimator for calculating, based on detected current of the motor and a command value, an estimated phase difference between the command value and the current; a low-speed motor rotational angle estimator for calculating, based on the detected current and a micro-step driving signal, an estimated motor rotational angle ¸ MEL at a low speed rotation; a high-speed motor rotational angle estimator for calculating, based on the estimated phase difference and the command value, an estimated motor rotational angle ¸ MEH at a high speed rotation; an addition unit for calculating, based on the command value, an estimated motor rotational angle ¸ ME by mixing the estimated motor rotational angles ¸ MEL and ¸ MEH at an appropriate rate; a detent torque estimator for calculating, based on the estimated motor rotational angle ¸ ME , estimated detent torque; and a compensation signal generator for generating a compensation signal based on the estimated detent torque and the estimated motor rotational angle ¸ ME .
