Book Description
A complete solution for problems of vibration control in structures that may be subject to a broadband primary vibration field, this book addresses the following steps: experimental identification of the dynamic model of the structure; optimal placement of sensors and actuators; formulation of control constraints in terms of controller frequency response shape; controller design and simulation; and controller implementation and rapid prototyping. The identification procedure is a gray-box approach tailored to the estimation of modal parameters of large-scale flexible structures. The actuator/sensor placement algorithm maximizes a modal controllability index improving the effectiveness of the control. Considering limitations of sensors and actuators, the controller is chosen as a stable, band-pass MIMO system resulting from the closed-form solution of a robust control problem. Experimental results on an aeronautical stiffened skin panel are presented using rapid-prototyping hardware.

Book Description
The thesis presents the results of an alytical investigation on using intelligen t control techniques to tackle the elastodynamic vibrations in flexible mechanis ms. Different adaptive control schemes based on fuzzy logic and neutral networks were designed and implanted to actively reduce the vibrations of the mechanism whose coupler link is synthesized with PZT sensor/actuator pairs bonded to its s urface at the high strain locations. A Fuzzy Logic Controller (FLC) was the first control scheme investigate d and implemented on the 4R mechanism. The knowledge about a system in fuzzy con troller less dependent on expert knowledge, an adaptive fuzzy logic controller b ased on expanding or contracting the membership functions of the control signal was implemented. Two adaptive neural network based controllers were also designed and i mplemented: the Single Network Decision (SNDC) and the Neural Internal Model Con trol (NIMC). The learning algorithm adopted to train the networks and to pursue an online adaptation is the backpropagation steepest descent method. Finally adaptive neuro-fuzzy inference system (ANFIS) controller was considered. ANFIS constructs a fuzzy system from the set of available data and t unes the associated membership functions through a neutral network type structur e. The simulation results showed effective reductions in the vibration a mplitudes at the mid-point of the coupler link for the different control scheme implemented. ANFIS controller proved to be the most powerful with an attenuation ratio of about 57%. Simulation results showed also the effectiveness and superi ority of neural controllers over the fuzzy logic based controllers.

Model Predictive Vibration Control

ISBN: 1447123336

Languages : en
Pages : 535
Book Description
Real-time model predictive controller (MPC) implementation in active vibration control (AVC) is often rendered difficult by fast sampling speeds and extensive actuator-deformation asymmetry. If the control of lightly damped mechanical structures is assumed, the region of attraction containing the set of allowable initial conditions requires a large prediction horizon, making the already computationally demanding on-line process even more complex. Model Predictive Vibration Control provides insight into the predictive control of lightly damped vibrating structures by exploring computationally efficient algorithms which are capable of low frequency vibration control with guaranteed stability and constraint feasibility. In addition to a theoretical primer on active vibration damping and model predictive control, Model Predictive Vibration Control provides a guide through the necessary steps in understanding the founding ideas of predictive control applied in AVC such as: · the implementation of computationally efficient algorithms · control strategies in simulation and experiment and · typical hardware requirements for piezoceramics actuated smart structures. The use of a simple laboratory model and inclusion of over 170 illustrations provides readers with clear and methodical explanations, making Model Predictive Vibration Control the ideal support material for graduates, researchers and industrial practitioners with an interest in efficient predictive control to be utilized in active vibration attenuation.
