  • Publication number: 20220166356
    Abstract: To provide a controller for rotary electric machine which can suppress the increase in the switching frequency by the voltage for estimation while reducing the estimation delay of the magnetic pole position (the rotational angle). A controller for rotary electric machine turns on and off switching devices which the inverter has and applies voltage to the winding, based on a comparison result between the voltage command and the carrier wave; generates the voltage command for estimation of a preliminarily set one period on a stationary coordinate system fixed to the winding; generates the carrier wave of the same one period as the one period of the voltage command for estimation; extracts the frequency component of the one period of the voltage command for estimation from the current detection value; and estimates a rotational angle based on the frequency component.

  • Publication number: 20200407078
    Abstract: A flying object control system includes a flying object, and a setting base that performs holding of the flying object and releasing the holding, the flying object and the setting base being communicable with each other. The flying object controls, upon receiving a takeoff instruction, thrust for taking off from a predetermined initial position, and when the thrust becomes greater than or equal to a first threshold, the flying object notifies the setting base of a start notification. Upon receiving the start notification, the setting base releases the holding of the flying object and notifies the flying object of a release completion notification. Upon receiving the release completion notification, the flying object takes off from the predetermined initial position by controlling the thrust in such a manner that the thrust becomes a second threshold smaller than the first threshold.

  • Patent number: 9132475
    Abstract: An object is to provide a mold molding method which can provide a high general-purpose property and can reduce a usage quantity of molding sand. In a method for molding a mold (sand mold) by self-hardening molding sand using a caking additive, the mold is molded by disposing hollow spheres each formed to have no clearance therein among molding sand mixed with the caking additive. Preferably, the hollow sphere may be formed by working two metal plates to semispherical shapes and then connecting the semispherical-shaped metal plates to each other by welding their respective whole peripheries. A specific gravity of the hollow sphere may be 0.5 to 2.0 times a specific gravity of the molding sand.
