Linear track control device and linear track system

A linear track system comprising:

• a conveyance path on which a stator is disposed;
• a first carrier that moves along the conveyance path;
• a second carrier disposed in a traveling direction of the first carrier;
• and
• linear track control device circuitry to drive the first carrier and the second carrier, wherein
• the linear track control device circuitry includes:
• drive control circuitry to control a current for generating a driving force between the stator and the first carrier, and to control a current for generating a driving force between the stator and the second carrier;
• and
• command generation circuitry to generate a time-series command defining at least one of a position, a speed, or an acceleration of the first carrier in time series and output the time-series command to the drive control circuitry, and
• the command generation circuitry includes:
• target setting circuitry to set a target value indicating a target of a position or a speed of the first carrier;
• correction coefficient determination circuitry to determine a correction coefficient for correcting any one of a position, a speed, or an acceleration of the first carrier based on a gap that is a relative value between position information indicating a position of the first carrier on the conveyance path and position information indicating a position of the second carrier on the conveyance path;
• and
• time-series command generation circuitry to generate the time-series command based on the target value and the correction coefficient, wherein
• the correction coefficient determination circuitry determines the correction coefficient by inputting a value of the gap to a correction function representing a relationship between the gap and the correction coefficient.
