Variable Structure Control – from Principles to Applications

The theory of variable structure systems (VSS) with sliding modes is currently one of the most significant research topics within the control engineering domain. Moreover, recently a number of important applications of the theory in the field of power electronics, motion control, robotics, bioprocess etc. have also been reported. Therefore, this paper presents a brief introduction to the theory...

Discrete Variable Structure Control

Dean of the Graduate College ii PREFACE The methodology of variable structure with sliding mode is proven to be very successful in controlling uncertain continuous-time dynamical systems. When the system is sampled or purely discrete, the invariance property of sliding mode, which is originally a continuous-time concept, no longer hold and the reaching condition has to be modiied to allow a pse...

Variable Impedance Control of Manipulator Robots Applied to Orthopedic Surgery

The main goal of this work is to use an impedance controller, implemented in a manipulator robot, with the aim of performing in orthopedic surgery. At first, some of the main progresses in robotic surgery are introduced as well as the possible application of this methodology in orthopedic surgery, namely in Hip Resurfacing. Then, the studied force controllers, namely the Impedance Control, some...

Variable Structure Control of Shape

A novel Shape Memory Alloy (SMA) actuator consisting of several thin NiTi bers woven in a counter rotating helical pattern around supporting disks is rst described. This structure accomplishes a highly eecient transformation between force and displacement overcoming the main mechanical drawback of shape memory alloys, that being limited strain. Time domain open loop experiments were then conduc...
