Abstract:
1. A control system for active vibration isolation of a supported payload, the control system comprising: a plurality of vibration signal transducers or sensors for supplying sensor signals; a plurality of actuators for vibration suppression; a control device for processing the sensor signals into actuator control signals, wherein the control device performs processing of position data and orientation data of all available sensors into a sensor control matrix ( processing units that generate a matrix of the form from position data and orientation data of the sensors and actuators to be input, where N g represents the number of sensors or actuators,  the respective positions and  the respective directions in relation to a fixed reference point of a dynamic system consisting of the supported payload and isolator modules, and based thereon, generate the sensor control matrix in the form for decoupling the axis input signals, or the actuator control matrix for distributing the calculated decoupled output axis signals onto actuator control signals, and with g ij being the orientation of the i-th sensor or actuator, correspondingly process the respective sensor signal or actuator control signals weighted proportionally relative to the j-th Cartesian degree of freedom.
