TY - CONF A1 - Höllthaler, Julia A1 - Hagl, Rainer A1 - Kennel, Ralph T1 - Bandwidth Improvements of Linear Direct Drives with a 100 kHz PWM-Frequency T2 - 2019 12th International Symposium on Linear Drives for Industry Applications (LDIA), Neuchatel, Switzerland N2 - A calculation method for a robust servo controller design depending on the sampling time and the processing dead time was developed for mechanically stiff drives. With a test stand for high dynamic and high positioning accuracy, the theoretical calculations for the high bandwidth improvements are verified. The test stand includes a voice coil motor and a power electronic with Gallium Nitride (GaN) power semiconductors for switching frequencies of more than 100kHz.
