ABSTRACT:
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.
