摘要： The inverter control device 10 controls the inverter 2 that generates the three-phase alternating current 200 for driving the AC motor 1. The PWM controller 12 executes the PWM control based on the torque command value TrqRef of the AC motor 1 to cause the inverter 2 to generate the three-phase alternating current 200. The one-pulse controller 13 executes one-pulse control based on the torque command value TrqRef to cause the inverter 2 to generate the three-phase alternating current 200. The switching controller 14 alternately switches the PWM control and the one-pulse control in the switching period for switching the control of the inverter 2 from the PWM control to the one-pulse control and controls the PWM controller 12 and one-pulse controller 13 so that one-pulse control is executed after the switching period has elapsed.

摘要： To provide a movable iron core linear actuator capable of properly adjusting an offset position without any increase in manufacturing cost or device size. A movable iron core linear actuator includes a magnetic circuit (mc) which causes a moving element (2) to reciprocate. The magnetic circuit (mc) includes an iron core (20) constituting the moving element (2), a stator core (10) including a facing portion (10c) which faces the iron core (20), a pair of permanent magnets (12a, 12b) disposed in the facing portion (10c) along a reciprocating direction and having inverted magnetic poles at their surfaces which face the iron core, and a coil (11) wound around the stator core (10). Energization to coil (11) causes the moving element (2) to reciprocate. When the coil (11) is not energized, offset force (F4) is applied to the moving element (2) by the magnetic flux produced by the permanent magnets (12a, 12b). A space portion (30) having low magnetic permeability compared with the stator core (10) is provided in a state in which a part of the facing portion (10c) is removed in an area, which is a magnetic flux path, between a part of the facing portion (10c) of the stator core (10) and the permanent magnet (12b). Thus, an offset position which is a balanced point of the gravity (mg) acting on the moving element (2) and the offset force (F4) by the permanent magnets (12) is changed to a position (ps2) from a position (ps4) that is the offset position in a case in which no space portion (30) is provided.

摘要： Multipliers 21a and 21b output values, which are obtained by multiplying a total drive command value E s by first and second gains G 1 and G 2 , respectively, as first and second drive command values E 1 and E 2 . Controllers 23a and 23b control first and second actuators (motors) 5 and 7, respectively, on the basis of the first and second drive command values. The detection values of the drive amounts of the actuators are denoted by E f1 and E f2 , respectively, and the detection value of the drive amount of a driven body is denoted by E f . A gain calculator 27 calculates the gains G 1 and G 2 on the basis of E f1 , E f and E f2 . An upper limit value of E f , which denotes the drive amount of the driven body, is denoted by L max . When E f1 , E f2 or E f approaches zero, the first gain G 1 is brought close to (E f1 - L max /2)/(E f - L max ).
