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.

摘要： In order to estimate a magnetic pole position of a permanent magnet type brushless motor, the following steps are conducted. A given &ggr; axis and a given &dgr; axis in an advanced from the &ggr; axis by an electrical angle of 90° are set. A closed-loop electric current control system in the &ggr; axis direction is formed while forming an open-loop electric current control system in the &dgr; axis direction. It is calculated an interference current generating in the &dgr; axis direction when a current command in the &ggr; axis direction is given as a stepwise alternating current command. The &ggr; axis is finely advanced by an angle of &Dgr;&thgr; when a sign of a product of an integral value of the interference current and a value of the current command in the &ggr; axis direction is positive. Alternatively, the &ggr; axis is finely delayed by an angle of &Dgr;&thgr; when the sign is negative. Thereby, the &ggr; axis is made accord with either a d axis as a true magnetic axis or with a -d axis advanced by 180° from the true magnetic axis.

摘要： In sensorless vector control performed through use of a rotation speed of a synchronous motor 6 and the position of a rotor, a positive current is caused to flow to a γ axis on the assumption that a “d” axis serving as a true magnetic axis is out of phase with the γ axis by only an angle of load θe, whereby torque which is proportional to iγ sin θe and directed toward the γ axis arises in the magnetic axis. Accordingly, a deviation between a d-q axis serving as a true magnetic axis and a γ-δ axis serving as a control axis is eliminated. Even if load is exerted on the motor, the γ axis serving as a control axis is constantly aligned with the “d” axis serving as the magnetic axis of the synchronous motor, thereby enabling excellent vector control.
摘要翻译：在通过使用同步电动机6的转速和转子位置进行的无传感器矢量控制中，假设以“d”为正磁轴的轴为正，则使正电流流向γ轴与γ轴异相仅具有负载角θe，由此在磁轴上产生与igammasinθe成正比且朝向γ轴的转矩。因此，消除了用作真磁轴的d-q轴与用作控制轴的γ-δ轴之间的偏差。即使负载施加在电动机上，作为控制轴的伽马轴与作为同步电动机的磁轴的“d”轴恒定对齐，由此能够进行良好的矢量控制。

摘要： A magnetic levitation and transport system has a plate-like moving element (SFT) which is moved by a linear motor disposed in a stator (STT). The moving element is moved vertically by first through fourth electromagnetic devices (MGV.sub.10 -MGV.sub.41), and fifth and sixth electromagnetic devices (MGH.sub.10 -MGH.sub.21) exert forces on the moving element in a horizontal direction perpendicular to the direction in which the moving element is moved. Gaps between the moving element and the electromagnetic devices are detected by gap sensors which produce gap data. In the vertical direction, for example, attractive force commands (f.sub.V1 -f.sub.V2) are produced from the outputs from a circuit for calculating the amount of feedback (10) which is supplied with the gap data (XV.sub.1 -XV.sub.4) and also with the output from a variable gain g.sub.V (l) generator (60) to which the position (l) of the center of gravity of the moving element is supplied. The attractive force commands are then linearized by linearizing circuits (71-74), and linearized outputs are applied to the electromagnetic devices. With this arrangement, the variable gains can be established by an analog circuit, and control gains in the respective control directions can be given independently of each other.

摘要： A electric motor control device is provided for controlling an electric motor which actuates a movable member of a machine through a transmitting mechanism. When a torque command is given as motion command signal (9) to servo device (3), servo device (3) sends input torque signal (12) corresponding to motion command signal (9) to electric motor (5), which is energized. Movable member (7) is thus moved, producing vibrations. Servo device (3) outputs input torque signal (11) equivalent to input torque signal (12), and input torque signal (11) and rotational speed signal (10) are stored in memory device (2). Analyzing device (1) analyzes the frequencies of input torque signal (11) and rotational speed signal (10) according to an FFT, and outputs analytical result (14).
