For a permanent magnet electrodynamic shaker (PMEDS), an LC filter is frequently connected in series to filter out the high-frequency voltage to avoid high-frequency harmonic acceleration of the PMEDS table. This paper use a simple current control loop to avoid high-frequency harmonic acceleration instead of an LC filter which may have large size and heavy weight in high-power applications. A cascade...
Compared to the conventional analog-circuit control and linear power amplifier for permanent-magnet electrodynamic shaker (PMEDS), a DSP-based digital current control with switched-mode power amplifier is proposed in this paper. A full-bridge converter is connected directly to PMEDS without LC filter in order to directly regulate the shaker current and simplify the digital current control. To meet...
