“…There are plenty of publications on the successful applications of the active vibration control methods in various systems under both broad-and narrowband vibrations. These processes include structures (Sommerfeldt and Tichy, 1988;Chang and Yang, 1995;Moshrefi-Torbati et al, 2006;Song et al, 2006), helicopters (Hall and Wereley, 1989;Bittanti et al, 1996), automotive engines (Bohn et al, 2004;Olsson, 2006), marine applications (Daley et al, 2004), magnetic bearings and rotor systems (Knospe et al, 1995;Fan and Lee, 1997;Knospe et al, 1997a;Zhou and Shi, 2001;Knospe, 2007;Tammi, 2007;Chen and Zhu, 2008).…”

Vibration is a phenomenon related to every physical system that has the potential to cause severe problems that range from increased structural fatigue to potential operator health hazards. The traditional approach to solve the vibration related problems is to dissipate the vibration energy through the addition of passive damping elements consisting of springs, masses and dampers. Even though these methods have been widely applied in all branches of industry, they are becoming increasingly inadequate in meeting the industrial standards of today. In the past decade the significant increase in the available computational power has given a rise to another approach to tackle the vibration related problems; namely the active control of vibrations, which is capable of meeting the tightened standards. In this approach, the vibrations are suppressed through the excitation of external energy in a suitable form into the system, resulting in the compensation of the vibrations. The use of this approach has enabled the mitigation of vibrations in very complex structures in a deterministic manner. The major benefit of the method is the change of the underlying design problem. Namely, the original structural design problem is converted into a standard control design problem, enabling the designer to use the very powerful tools of control theory. In this thesis, a novel method for active vibration mitigation is presented. The proposed approach shares many similarities with the existing model-based methods while addressing many of the drawbacks and problems encountered with the current approaches. The proposed method is a generic nonlinear control law capable in the simultaneous suppression of multiple tonal disturbances in multiple dimensions. The control design procedure is simplified such that the number of free parameters is minimal and the impact of these parameters on the process performance is transparent. Such an approach enables the method to be applied by an industrial system specialist with possibly very little experience in control theory, unlike what is the case with the most of the existing methods. In addition, the essential tools for the performance and stability evaluation of the obtained control law are presented in detail with the focus being in the problems commonly encountered in the practical implementation. This thesis consists of a summary and five publications with the focus being on the control design, performance analysis and test-bed implementation in several industrial processes. An extensive comparison of the proposed method against the existing linear control approaches is also included in this work.

“…Other researchers have advocated the use of film-type sensors and actuators for vibration control in the form of piezoelectric patches. Applications to space structure problems are described in [11][12][13][14][15][16]. From these works, it is clear that the control influences provided are small and suitable for suppressing low levels of vibration.…”

Many space vehicles have been launched with large flexible components such as booms and solar arrays. These large space structures may require active shape control given the possibility of lightly damped vibrations. Such vibrations can be controlled using a collection of control moment gyros, which consist of a spinning wheel in gimbals and produce a torque when the orientation of the wheel is changed. This study investigates the optimal distribution of these control moment gyros on large space structures for vibration suppression. Initially, a continuum model is adopted that represents the distribution of control moment gyros by a continuous distribution of stored angular momentum (gyricity). The optimal control solution for the gimbal motions (for a given gyricity distribution) is then optimized with respect to the gyricity distribution. Further investigation considers discrete parameter models of beam and a plate structures with evenly placed discrete pointwise control moment gyros. Numerical optimization of a suitable cost function allocates the amount of stored angular momentum possessed by these control moment gyros.
