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 cascade block ( 53 ) for the axis signals containing several biquad filters ( 531, 532, 533, 534, 535 ), and with an output signal calculation block ( 55 ) for calculating digital actuator actuation signals. A digital signal processor ( 9 ) is connected in parallel with the FPGA system ( 5 ) in order to calculate controls with low phase loss requirements.
