Shape Optimization of Piezoelectric Sensors or Actuators for the Control of Plates
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...
متن کاملOptimal Shape Control of Composite Thin Plates with Piezoelectric Actuators
Emerging technologies in microsensing, microactuation, active airfoils, turbine blades, and large, lightweight, flexible space structures can benefit from piezoelectric actuators for active shape control. Piezoelectric materials develop strain under applied voltage which induces structural deflection. This article presents analytical models, FEM solution, and optimal shape control of composite ...
متن کاملOPTIMIZATION OF PLACEMENTVOLTAGE OF PIEZOELECTRIC ACTUATORS ON AN L-SHAPE BEAM USING PARTICLE SWARM OPTIMIZATION ALGORITHM
In this paper, controlling the location of the tip of an L-shape beam under gravity field is investigated. The beam is covered with piezoelectric patches. The gravity filed moves the tip of beam downward and the actuators with induced voltage move the tip to the previous location. to optimize the best location and voltages for actuators, the particle swarm optimization algorithm code is develop...
متن کاملA Higher-Order FEM for Vibration Control of Composite Plates with Distributed Piezoelectric Sensors and Actuators
The active vibration control of laminated composite plates using distributed piezoelectric sensors and actuators (Fig. 1) is studied numerically with a higher-order finite element method (FEM). Reddy’s simplified higher-order theory for transverse shear deformation, which is found to be much more accurate for both thin and thick composite plates as compared with other theories, is employed for ...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
