Abstract
Control of an active vibration isolation system with a digital controller, which includes an FPGA system () as the control unit. The FPGA system () is made up of freely programmable gate arrays with a sensor control matrix (), which calculates axis signals in required degrees of freedom, with a control cascade block () for the axis signals containing several biquad filters (), and with an output signal calculation block () for calculating digital actuator actuation signals. A digital signal processor () is connected in parallel with the FPGA system () in order to calculate controls with low phase loss requirements.
