Active damping based on decoupled collocated control
Publication Year: 2005, Page(s):135 - 145
Cited by: Papers (17)Robust stability of controlled mechanical systems is often obtained using collocated actuator-sensor-pairs. Collocation enables the implementation of a passive control law, which is robustly stable, irrespective of structural modeling errors. Within the context of vibration control, this knowledge is used to obtain robust active damping. However, collocated control is inherently in terms of "local... View full abstract»

Broad-band active vibration suppression using PPF focused on industrial application
Publication Year: 2005, Page(s):146 - 153
Cited by: Papers (18)Due to the demand for higher accuracy and lower acoustic noise levels, there is a growing interest for active vibration suppression in industrial application. Many control concepts have been proposed in this field that are suited to introduce damping in systems with a large number of modes. However, tuning is often focussed on reduction of one dominant mode. Such control approaches are less transp... View full abstract»

Viscous control of homogeneous ER fluid using a variable structure control
Publication Year: 2005, Page(s):154 - 160
Cited by: Papers (9)Homogeneous electrorheological (ER) fluid is a smart fluid whose appearance viscous coefficient can be controlled by applying an electric field. Therefore, the application of this fluid can create a damping device in a mechanical system. However, the ER effect of the fluid is easily changed by shear rate or temperature variation. In this study, a viscous coefficient control method using a variable... View full abstract»

Modeling, fabrication, and validation of a high-performance 2-DoF piezoactuator for micromanipulation
Publication Year: 2005, Page(s):161 - 171
Cited by: Papers (58) | Patents (1)A high-performance compact micromanipulation system is presented. The system, called the microgripper microrobot on chip (MMOC), was developed at Laboratoire d'Automatique de Besancon (LAB), France. Two main parts in the MMOC design of the MMOC are discussed: 1) the piezoactuator and 2) the end-effectors. The micromanipulator is partially fabricated in a clean room and the piezoactuator system has... View full abstract»

Limit cycles in control systems employing smart actuators with hysteresis
Publication Year: 2005, Page(s):172 - 180
Cited by: Papers (13) | Patents (2)This paper presents theoretical and experimental results concerning a feedback control system employing a Terfenol-D-based smart actuator. Such magnetostrictive devices exhibit significant hysteresis, which, under some conditions, can generate self-sustained periodic oscillations in the control loop. The paper proposes a general procedure to find these conditions and to compute this periodic solut... View full abstract»

Flexure control using piezostack actuators: design and implementation
Publication Year: 2005, Page(s):181 - 188
Cited by: Papers (9)In this paper, the application of high control authority piezostack actuators (PSAs) for active vibration control of large-scale flexible structures is studied. The idea is to add PSAs at appropriate locations of a flexible structure in order to strengthen its stiffness characteristics. In this regard, a flexible link of a macro-micro manipulator system actuated with PSAs is considered. The design... View full abstract»

Differential hysteresis modeling of a shape memory alloy wire actuator
Publication Year: 2005, Page(s):189 - 197
Cited by: Papers (77)In this paper, we develop a complete mathematical model of a shape memory alloy (SMA) wire actuated by an electric current and a bias spring. The operation of the SMA actuator involves different physical phenomena, such as heat transfer, phase transformation with temperature hysteresis, stress-strain variations and electrical resistance variation accompanying the phase transformation. We model eac... View full abstract»

Robust dynamic experimental identification of robots with set membership uncertainty
Publication Year: 2005, Page(s):253 - 256
Cited by: Papers (14)This paper focuses on robust dynamic identification of robots with set membership uncertainty. The error, taken additive on model output (input motor torque), is only assumed to be bounded. Three bounded-error recursive algorithms are implemented to outer-bound the solution parameter set with ellipsoids or parallelotopes. Experimental results are presented for a two degrees-of-freedom SCARA robot. View full abstract»
