    • In a transfer device for workpiece carriers (18), with a number of segments (10, 10′, 10″) in which a control unit (14, 14′, 14″) respectively activates a linear motor (12, 12′, 12″), in a phase of the transfer of the workpiece carrier (18) from a first segment (10) to a neighbouring segment (10′) synchronization of the linear motors (12, 12″) is no longer effected on the basis of control commands of a central controller but instead the control unit (14) of the first segment (10) makes itself the master (S18) and subjugates the control unit (14′) of the neighbouring segment (10′) as the slave (S20). A position measuring device (22, 24) makes it possible for the master control unit (14) to carry out speed control for the workpiece carrier (18). The control unit (14′) receives information on the commutation angle and the actual force value and can therefore issue the control commands to the associated linear motor (12′) for the control process.

    • A method for identifying a control path of a controlled system, and more particularly to a method for identifying a control path in the presence of deterministic perturbations is described. At least one deterministic perturbation correcting signal is determined in a first identification process, and the perturbation correcting signal is stored in the form of a function. A control path of the controlled system is identified in a second identification process by adding to the controlled system the at least one stored deterministic perturbation correcting signal with a negative feedback. The method can be used with machine tools, production machines and/or robots which demand a high control accuracy and/or a high-quality control characteristic. In particular, perturbation effects due to slot latching in motors, in particular linear motors, can be minimized.
    • 描述了用于识别受控系统的控制路径的方法,并且更具体地涉及用于在存在确定性扰动的情况下识别控制路径的方法。 在第一识别处理中确定至少一个确定性扰动校正信号,并且以功能的形式存储扰动校正信号。 通过向受控系统添加至少一个具有负反馈的存储的确定性扰动校正信号,在第二识别处理中识别受控系统的控制路径。 该方法可用于需要高控制精度和/或高质量控制特性的机床,生产机器和/或机器人。 特别地,可以将由于电动机中的槽锁定,特别是线性电动机引起的扰动效应最小化。

    • The invention relates to a method for protecting against over voltage that is simple to produce, economical, compact and is simultaneously effective against over voltage for a converter (8) provided for supplying an electric motor (1) comprising at least one motor phase (L1, L2, L3). Said converter comprises an electric intermediate circuit (10) and several half-bridges (13a, 13b, 13c) that are connected in parallel in the intermediate circuit and respectively comprise a circuit breaker (15a, 15b, 15c) on the high potential side and a circuit breaker (17a, 17b, 17c) on the low potential side, in addition to an intermediately connected phase connection (14a, 14b, 14c). According to the invention, an intermediate circuit voltage (Uz) is detected and the or each motor phase (L1,L2,L3) is short-circuited by controlling the circuit breaker (15a, 15b, 15c) on the high potential side or the circuit breaker (17a, 17b, 17c) on the low potential side, if the intermediate circuit voltage (Uz) exceeds a predetermined maximum value. The invention also relates to a motor module (3) that comprises the converter (8) and a protection logic (22) for carrying out said method.
