Abstract: A method for standstill control of a multi-body system (MKS) having at least one drive body and at least one friction body mechanically coupled to the drive body. A static friction acts on the friction body, a velocity of one of the bodies of the MKS is determined as measurement velocity subject to a measurement noise and converted in a dead zone element to a dead zone velocity.

The dead zone velocity is provided to a velocity controller as an actual velocity for controlling.

Abstract: Method for time synchronization in a network between at least one master and at least one slave, which is an interrupt-capable network component and uses a timer, which accesses a slave time to generate at least one interrupt recurring at a predefined cycle duration, at a respective trigger point in time that is synchronized with the slave time. When a synchronization message arrives, a time offset between the master time and the slave time is determined in the slave, and a time fraction is determined from the time offset, which corresponds to an integer multiple of the predefined cycle duration of the at least one interrupt. An interrupt offset is then determined from the time fraction and the time offset. At least one time jump is carried out by a synchronization unit in the slave to correct the time offset.

Abstract: A method and network for time synchronization of at least one master and at least one slave, which is an interrupt-capable network component. A time offset between a master time and a slave time is determined. A first time fraction of the determined time offset is adjusted in first synchronization step(s) using a time jump. The first time fraction corresponds to an integer multiple of the cycle duration of the interrupt(s) and a second time fraction of the determined time offset is adjusted in a number of successive second synchronization steps using frequency alignment and/or a time jump. The second time fraction corresponds to a non-integer multiple from the range ]?1.0[ and ]0.1[ of cycle duration of the interrupt(s). In each of the number of second synchronization steps, an actual occurring cycle duration of the interrupt(s) deviates from the predefined cycle duration by no more than a predefined deviation.

Abstract: For improved control and planning of a movement of the object in relation to a transport unit of a transport system, the transport unit is moved along a predefined transport trajectory with respect to a reference coordinate system. Embodiments provide a synchronous phase, in which a movement of an object point of the object along an object path with respect to a transport unit coordinate system, different from the reference coordinate system, is predefined during the synchronous phase. The transport unit coordinate system containing the transport unit is moved along the transport trajectory. At least one path point of the object path is converted from the transport unit coordinate system to a base coordinate system in order to control the movement of the object point along the object path with respect to the base coordinate system.

After the pause, the first subscriber continues to transmit the data frames with a granularity of one data symbol.
