Shape Optimization of Piezoelectric Sensors or Actuators for the Control of Plates

چکیده
This paper deals with a new method to control flexible structures by designing noncollocated sensors and actuators satisfying a pseudo-collocation criterion in the low-frequency domain. This technique is applied to a simply supported plate with a point force actuator and a piezoelectric sensor, for which we give some theoretical and numerical results. We also compute low-order controllers which stabilize pseudo-collocated systems and the closed-loop behavior show that this approach is very promising.
