Optimal Actuator and Sensor Placement for Active Sensing
In active sensing, actuators are used to impart user-defined energy into a structure from which resulting sensor responses may be mined for useful information regarding the structure’s health. Optimal actuator-sensor placement works to maximize the observability of this information given two primary constraints: the number of actuators and sensors available for the network and the power availab...
متن کاملA Disturbance Rejection Approach to Actuator and Sensor Placement
For various reasons as discussed for instance in [1], the selection of actuator and sensor positions is still ad hoc. This is especially true for exible structures where many candidate con gurations can exist. This study is an attempt to make the selection process more methodical. One approach to actuator and sensor placement is to optimize a closed loop performance metric directly by selecting...
متن کاملVibration Attenuation Timoshenko Beam Based on Optimal Placement Sensors/Actuators PZT Patches with LQR-MOPSO
The main objective of this study is to reduce optimal vibration suppression of Timoshenko beam under non-periodic step and impulse inputs. Cantilever beam was modeled by Timoshenko theory and finite element numerical method. Stiffness (K), mass (M), and damping (C) matrices are extracted. Then, in order to control structure vibration, piezoelectric patches were used due to simultaneous dual beh...
متن کاملOptimal Locations on Timoshenko Beam with PZT S/A for Suppressing 2Dof Vibration Based on LQR-MOPSO
Neutralization of external stimuli in dynamic systems has the major role in health, life, and function of the system. Today, dynamic systems are exposed to unpredicted factors. If the factors are not considered, it will lead to irreparable damages in energy consumption and manufacturing systems. Continuous systems such as beams, plates, shells, and panels that have many applications in differen...
متن کاملOptimization Strategy for Actuator and Sensor Placement in Active Structural Acoustic Control
In active structural acoustic control the goal is to reduce the sound radiation of a structure by means of changing the vibrational behaviour of that structure. The performance of such an active control system is to a large extent determined by the locations of the actuators and sensors. In this work an approach is presented for the optimization of the actuator and sensor locations. The approac...
