High-precision mechatronic equipment often benefits from or even needs vibration isolation to function within specification. Examples of such equipment include metrology devices, space instrumentation and lithography assemblies. Vibration isolation is often the function of the mounting between the equipment and the floor or rest of the machine....

Imagery collected from space provides very useful information about our planet. Today there are many Earth Observation satellites in orbit which allow us to collect information which is used for environmental monitoring, response to catastrophes, surveillance and security, urban planning, economic analysis and many other applications. Thus,...

The high-tech industry is constantly searching for methods to make more efficient, more accurate, and faster machines. One of the methods to improve the performance of these machines is active vibration control(AVC) which can help to achieve faster transient responses. One of the ways to achieve this is better controllability which means more...

Piezo actuators have very desirable properties, such as a high stiffness and extreme position resolution, but suffer from electromechanical resonances that complicate their use in high-speed applications. These resonances can be minimized by using resistive or resistive-inductive damping. In this paper a comprehensive theory is presented...

Piezoelectric actuators are a very attractive technology for active optics mechanisms in space applications due to their very high precision and reliability. However, self-heating of these actuators may be limit their use in space or under high loads, due to the limited ability to evacuate heat. Test procedures that reproduce the operational...

Metamaterials are engineered structures that exhibit exotic properties that are obtained from the unit cell geometry and arrangement instead of its constituent materials. Mechanical metamaterials alter mechanical stimuli and they can exhibit unique elastic properties such as negative stiffness, shear modulus, bulk modulus, and Poisson’s ratio....

The need for higher spatio-temporal resolution Earth observation increases rapidly. To fill this need, the Deployable Space Telescope (DST) project aims to make a light-weight, low-volume deployable telescope. In doing so, the achievable ground resolution is high while the cost per telescope stays low. This allows for the DST to be used in...

As systems become more lightweight, to satisfy inertia and size requirements, vibration becomes a prominent factor in their dynamics. This vibration is undesirable and various suppression methods exist such as passive, semi-active, and active. In this thesis, active control methods are explored for this purpose. The present technology utilizes...
