Monotonic and Fatigue Performance of RC Beams Strengthened with Externally Post-Tensioned CFRP Tendons
(University of Waterloo, 2007-05-04)External post-tensioning is an attractive technique for strengthening reinforced concrete structures because of its ability to actively control stresses and deflections, speed of installation, minimum interruption for the ... -
Nano Positioning Control Using Magnetostrictive Actuators
(University of Waterloo, 2007-05-18)The focus of this thesis is on the development of control systems for nano- positioning actuators using magnetostrictive materials. Magnetostrictive materials have large strokes and fast responses. However, they are ... -
Regulation of Hysteretic Systems with Preisach Representation
(University of Waterloo, 2009-09-30)Piezoelectric actuators are well suited for high precision mechanical and electrical engineering applications. However, its performance in regulator configurations has been limited due to hysteresis. The hysteresis in these ... -
A study of the reduced-order John Shaw SMA model and its extension for control applications
(University of Waterloo, 2012-04-27)SMA belongs to a class of so-called “smart materials” which possess properties that can be controlled by application of various types of stimuli – stress, temperature, electric field or magnetic field. In particular, SMA ...
