Control device and wire connection determination method
A control device includes: an output unit configured to select a motor and output a drive command to a motor drive unit that should be connected to the selected motor so that the selected motor executes a predetermined feed operation; an acquisition unit configured to acquire feedback information from each of the multiple motor drive units; and a wire connection determination unit configured to determine, based on the feedback information, whether the selected motor is connected to the motor drive unit that should be connected to the selected motor, by a power line and a feedback line.
Mid-bus voltage generation via idle phases in a linear motor track system
Drive coils in sections of a linear motor track that are normally used to electromagnetically propel movers along the track when such movers are nearby can be used to generate a mid-bus voltage for the section when not being used to propel movers. Such drive coils not being used to propel movers are considered idle and available for mid-bus voltage generation. The mid-bus voltage, and a full-bus voltage from which the mid-bus voltage is derived, in turn, can be applied across other drive coils that are near movers with varying polarities and magnitudes to propel movers along the track. Track sensors can be positioned along the track to detect presences or absences of movers with respect to drive coils for determining propulsion of such movers or generation of the mid-bus voltage. Accordingly, power supplies can be used more efficiently by not requiring them to generate mid-bus voltages in addition to full-bus voltages and DC references.

System and method for scalable real-time micro-object position control with the aid of a digital computer
The system and method described below allow for real-time control over positioning of a micro-object. A movement of at least one micro-object suspended in a medium can be induced by a generation of one or more forces by electrodes proximate to the micro-object. Prior to inducing the movement, a simulation is used to develop a model describing a parameter of an interaction between each of the electrodes and the micro-object. A function describing the forces generated by an electrode and an extent of the movement induced due to the forces is generated using the model. The function is used to design closed loop policy control scheme for moving the micro-object towards a desired position. The position of the micro-object is tracked and taken into account when generating control signals in the scheme.

Associated systems are described herein.
