Control of an active vibration isolation system with a digital controller, which includes an FPGA system (5) as the control unit. The FPGA system (5) is made up of freely programmable gate arrays with a sensor control matrix (51), which calculates axis signals in required degrees of freedom, with a control...http://www.google.de/patents/US20070043479?utm_source=gb-gplus-sharePatent US20070043479 - Control of an active vibration isolation system
