Abstract in different language: The paper deals with the optimization of active vibration suppression of plate demonstrator equipped by regular grid of 5x5 actuators and their collocated 5x5 sensors realized by planar piezo patches. Robust H-infinity design with fixed order controller of predefined structure and LQR design using implementation with the states observer have been investigated. The influence of different boundary conditions (examples in Fig. 1) of the plate to efficiency of different control law concepts is the main topic of research. The ideal target is an easy tunable, scalable, active vibration suppression control law, defined by a limited number of independent parameters and optimized dominantly based on the local dynamical properties of the compact actuator-sensor-matrices and only finally tuned taking into account the particular global mechanical configurations (e.g. boundary conditions).
