This paper presents numerical analyses of the impact of the size of the sensor-actuator part
on sensor-actuator efficiency. For that purpose, numerical models of a steel plate clamped on
all sides were created with two piezoelectric actuators attached to it. One was used to excite
the plate and the second (which could be either a standard actuator or a sensor-actuator,
having different shapes and sensor part size) to reduce plates vibrations. Harmonic analyses
were performed with the goal function being the minimum of the displacement vector sum
of n nodes, where n can have different values depending on the case study.
