Title: Control device for induction motor
Inventor: YURA MOTOSUMI
IPC: H02P21/22
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To realize speed sensorless vector control by a simple arithmetic process suited for a control device, by compensating an error of an estimated value of a rotational speed obtained from a slip frequency estimated value by a compensation value of a speed estimated value obtained by amplifying an excitation current in-phase voltage command. SOLUTION: A 3-phase/2-phase converter 16 calculates by arithmetic operation an excitation current detection value ild and a torque current detection value ilq from an instantaneous value iu, iv, iw, of a motor current and a sin ωt/cos ωt signal output by a 2-phase sinusoidal wave generator 22. A slip frequency estimated value is subtracted from a motor current angular frequency ω, so that an estimated value of a rotational speed of a motor is obtained. In the case of providing an error in the estimated value of the rotational speed, an excitation current in-phase voltage command is amplified, a compensation value of the speed estimated value is obtained. By this way, speed sensorless vector control, including control of a motor current, can be realized by algorithm suited for a system using a microprocessor or the like.

Filed: 1979-07-24
Abstract: PURPOSE:To always keep a constant height from the surface of the sea for the antenna, by shifting up and down the antenna supported in the free up-down movable way by the maritime structure in accordance with the tide level. CONSTITUTION:Plural numbers of radial horizontal protruded components 5 are fixed at the upper end of steel tower 3 fixed onto maritime structure 2, and pulley 6 is attached to the lower face of each component 5. Antenna 1 is made linear and hanged down vertically on cord 7 hooked to pulley 6, and balancing weight 8 is attached to one end of cord 7. At the same time, float 10 is attached to the lower end of antenna 1 via cord 9. And float 10 is always under the sea level with a certain depth in order to secure a balance between the upward force produced by weight 8 and the buoyancy and the downward force by the empty weight. As a result, float 10 shifts up and down with the up-down movement of the sea level caused by the change of the tide level, and accordingly both weight 8 and antenna 1 shift. Thus a constant height from the sea level can always be secured for antenna 1.
