Shape control of a beam using piezoelectric actuators
This paper presents the analytical and experimental results on optimal placement of piezoceramic actuators for shape control of beam structures. The objective is to determine the optimum piezoceramic actuator locations and voltages to minimize the error between the desired shape and the achieved shape. The analytical model for predicting beam deformation due to a piezoelectric actuator is based...
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 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 کاملNonlinear Position Control of a Flexible Beam Using Shape Memory Alloy Actuators
This paper presents a nonlinear control scheme for position control of a flexible beam system using Shape Memory Alloy (SMA) actuators. Due to their interesting properties such as force generation capacity, possibility of miniaturization, and power consumption, these devices have been gaining increased popularity in the past few years. However, SMA actuators possess undesirable characteristics ...
متن کاملControl of Piezoelectric Actuators Using Analog Sliding Mode Controller
This work aims the precise control of the piezoelectric actuators that can theoretically provide unlimited motion resolution. For this purpose Sliding Mode Controller (SMC) is used. The proposed algorithm is known to have order of sampling time square and therefore faster application than DSP was required. The application of the algorithm via analog electronics is suggested. Preliminary work, s...
