    摘要: A multiple pulse-width modulation power conversion device for variable-speed drive of a three-phase AC motor comprises three units (11 1 , 11 2 , and 11 3 ), each unit including n (n ≧ 2) batteries (12 11 , 12 12 , and 12 13 ), each made up of a DC power supply or at least one battery cell, and n power converters (13 11 , 13 12 , and 13 13 ) for converting the DC power of each of these batteries to single-phase AC power. Single-phase AC terminals within each unit are connected in series, and of the single-phase AC terminals within each unit, one of the single-phase AC terminals that is not connected to the single-phase AC terminal of another power converter is connected to a star connection, and the other is connected to a respective one of three input terminals of a three-phase AC motor. The power conversion device further comprises control circuits (14 11 , 14 12 , ... 14 33 ) for controlling the power converters such that the AC outputs applied to the single-phase AC terminals of the n power converters within each unit are of the same phase, and further, for effecting multiple pulse-width modulation such that the AC outputs from the three units are separated by an electrical angle of 120°.

    摘要: First, second and third compensation signals are generated from the information on the position and speed of the first servo system having a speed control loop as a minor loop. The speed error of the speed control loop of the second servo system which has the speed control loop as a minor loop and uses a signal obtained by sampling the position detection signal, executing a digital calculation process on the sampled signal to obtain a speed signal and integrating the speed signal as a position command signal or a signal obtained by sampling the position detection signal of the first servo system and executing a digital calculation process on the sampled signal as a position command signal is compensated by the first, second and third compensation signals. Thus, even in cases where the acceleration and deceleration of the first servo system are executed even at constant power, positional synchronizing error is not generated. The accurate positional synchronizing control between two servo systems having different response characteristics can be achieved.

    摘要: In order to operate the relative posture between a work (4) gripped by a robot (1) and an arbitrary work point (A) without changing the position of a certain point (P), the work point (A) is defined on the reference coordinates of the robot (1) and when the work (4) gripped by the robot (1) is subjected to a teaching operation with respect to the work point (A), the work point (A) is temporarily controlled as if it were the end effector of a robot control point (R). As the work (4) is rotated around the work point (A), the posture of the work (4) is changed to a desired relative posture with respect to the work point (A). In this manner, the posture of the work (4) gripped by the robot can be changed to a desired relative posture within a short period with respect to the work point (A) and the teaching time can be reduced.
