摘要： In order to improve the adaptation of a long stator linear motor to requirements or conditions of individual transport units or of the transport track it is foreseen, that the control variables (StG) of a driving coil (7, 8) of long stator linear motor are superimposed with an excitation signal (AS) with a predetermined frequency band, wherein actual variables (IG) of the driving coil control are determined, from the control variables (StGAS) superimposed with the excitation signal (AS) and from the determined actual variables (IG) a frequency response is determined and from the frequency response the control parameters (RP) for this transport unit (Tx) are determined and the transport unit (Tx) is controlled using these determined control parameters (RP) for movement along the transport track.

摘要： In order to improve the adaptation of a long stator linear motor to requirements or conditions of individual transport units or of the transport track it is foreseen, that a movement profile is preset for the transport unit (Tx), which is followed by the transport unit (Tx), in doing so at least one system parameter of a model of the control system (21) is determined by means of a parameter estimation method, and the value of the system parameter over time is collected and from the variation over time a wear condition of the transport unit (Tx) and/or of the transport track is deduced.

摘要： A method for controlling a drive of a machine having at least one first roll element, which rolls with a surface on a counter surface at least in subintervals of a revolution cycle with the action of a contact force under elastic deformation, that includes a speed correction method, which automatically compensates for deformation-related deviations of the peripheral velocity of the first roll element by way of an adaptation of the setpoint value for the velocity of the first roll element, and a retrospective method, which automatically compensates for deviations of the speed consistency of the first roll element within a revolution cycle by applying a correction signal determined from the curve of a control variable, in particular an actual velocity or actual position of the first roll element, in a preceding revolution cycle or in multiple preceding revolution cycles, are applied in combination.
