    <title language="eng">Bandwidth Improvements for Current Control Loops with a 100 kHz PWM Frequency and GaN Power Semiconductors</title>
    <abstract language="eng">A discrete-time design method for a robust current controller of a servo drive has been developed. It takes the sampling time, the processing dead time and the dynamic behavior of the A/D converter into account. The theoretical calculations are verified using a test stand for high dynamics. The test stand includes a voice coil motor and power electronics with Gallium Nitride (GaN) power semiconductors for switching frequencies of more than 100 kHz. The bandwidth of the current control loop can be improved from typically 1 kHz to 1.5 kHz with insulated-gate bipolar transistor (IGBT) power semiconductors in state-of-the-art motion control systems to 10 kHz and more.</abstract>

    <title language="eng">Influence of the PWM Frequency on Dynamic and Position Stability of Servo Drives</title>
    <abstract language="eng">The dynamic behavior and position stability of servo drives are influenced by many parameters. One major influencing parameter is the pulse width modulation (PWM) frequency. With inverters based on wide bandgap semiconductors, the PWM frequency can be increased. This enables a substantial increase in the current control bandwidth. The paper focuses on the influence of the PWM frequency on the dynamics of control loops and position stability, which are derived from theoretical correlations. The theory is verified using a test bench for high dynamic and position stability. The test bench is equipped with a voice coil motor and power electronic with gallium nitride (GaN) power semiconductors for switching frequencies of 100kHz and over. The achieved position stability, measured with a laser-based comparator at the tool center point, is lower than "+-1nm" with a standard deviation of "0.16nm" at a PWM frequency of "f_PWM=100kHz".</abstract>

    <abstract language="eng">In this work, the limitations of a miniature drive concerning high dynamics with coincident high position accuracy are examined. Therefore, the entire system is considered and optimized. A complete discrete time model is developed and the maximum possible bandwidth is determined. Influencing parameters such as position evaluation, digitization of the feedback variables and digital pulse width modulation are examined. A miniature drive is developed in order to realize and verify high dynamics and position stability in sub nanometer range.</abstract>
