Abstract
The invention relates to a control system for active vibration isolation of a supported payload with a control device that comprises a processing unit (41) for processing position data and orientation data of all available sensors to supply a sensor control matrix, as well as for subsequent calculation of axis input signals in orthogonal degrees of freedom from the sensor signals and the sensor control matrix, a downstream control-path cascade block (42) for processing axis input signals into axis output signals in orthogonal degrees of freedom, and a downstream processing unit (43) for processing position data and orientation data of all available actuators for vibration suppression into an actuator control matrix, as well as for subsequent calculation of actuator control signals from the axis output signals and the actuator control matrix.
