It presents a procedure for estimating the maximum arithmetic error of fixed-point operations inside a modeled control loop, which can be used to verify compliance with a defined precision. Additionally, it shows the results of a runtime analysis for different numerical data types in combination with two fixed-point operations: addition and multiplication. In order to improve the fixed-point performance for MATLAB® Simulink® models, two optimized implementations are provided, which can improve the fixed-point operations by a factor up to 3, compared to the automatically generated operation implementations. The paper results are based on the MATLAB® R2022b release.

As the motor current is proportional to torque or force, the current control loop dynamics is crucial for all operating modes. In production machines used in the semiconductor industry, it is particularly important that the bandwidths of the control loops are continuously increased. It is thus important to take the dependency of motor resistance and inductance on frequency in control loop design into consideration. As the switching frequencies of wide-bandgap semiconductors increase, the effect becomes even more significant. This paper discusses the influence of frequency-dependent resistance and inductance on the behavior of a PI current controller. A design method for an optimized and robust current controller is then presented on this basis. Verification is performed with two completely different servo motors-a 3-phase permanent magnet synchronous motor and a high-dynamic optimized voice-coil motor.

Strain gauges are standard devices for quantifying the deformation. In this paper, a device determining the torque based on a measured relative distortion of a torsional flexible body is presented. Two position measuring devices are used to determine the relative distortion. The design criteria for the flexible body of the sensor are discussed. A prototype using the proposed measurement principle was built up and analyzed regarding the achievable accuracy of the torque measurement at pure torsional loads and also under disturbing loads. The results show a high accuracy in the torque measurement with a linearity error in the range of 0.11% of the maximum torque. The influence of disturbing loads on the torque measurement can be neglected, which is an advantage compared to other torque sensors.

However, the use of digitalisation technologies is also associated with efforts such as costs, CO2 emissions, and raw material consumption. When planning or deciding on the digitalisation of manufacturing systems, it is therefore necessary to assess whether these technologies pay off in terms of sustainability over their life cycle. This literature review (based on the PRISMA guidelines) analyses the relevance of sustainability assessment and its methods for the digitalisation of production in research. The review reveals that research focuses on the benefits of digitalisation technologies in manufacturing, while the assessment of efforts and their benefits is in its infancy. There is a need for further research on holistic assessment methods for digitalisation technologies. In particular, there is a lack of assessment methods that consistently link the economic and environmental dimensions of sustainability, and there is also a lack of guidance for the application of assessment methods in production.
