Experimental/analytical determination of optimal piezoelectric actuator locations on complex structures based on the actuator power factor
The actuator power factor is defined as the ratio of the total dissipative mechanical power of a PZT actuator to the total supplied electrical power to the PZT actuator. If measured experimentally, it can be used to optimize the actuator location and configuration for complex structures. The …

The optimal design of transducers for active control of multiple-frequency structural sound radiation
… excitation. The control is achieved by use of piezoelectric (PZT) actuators. An optimization procedure is developed to find the optimal locations of actuators with which the radiated sound power from the plate is minimized. Also, the optimization of the piezoelectric actuator locations has been …
