Controllable Damping Magnetorheological Elastomer Meniscus

ACS Biomaterials Science & Engineering, 2022
The human healthy meniscus fulfills key biomechanical functions in the tibiofemoral (knee) joint. Meniscal injury leads to an increased risk for symptomatic osteoarthritis. In order to prevent osteoarthritis, many researchers have put efforts into developing new-type meniscal substitute materials.

Damping control of variable damping compliant actuators

2015 IEEE International Conference on Robotics and Automation (ICRA), 2015
The development of variable impedance actuators (VIAs) has highlighted the need for proper control of passive impedance to attain suitable interaction performance. Until recently the regulation of the intrinsic impedance in VIAs is achieved in an open-loop model-based manner, mainly due to the lack of physical sensors capable of measuring impedance ...

Power System Oscillations Damping Using UPFC Damping Controller

2010 3rd International Conference on Emerging Trends in Engineering and Technology, 2010
Low frequency electromechanical oscillations are inevitable characteristics of power systems and they greatly affect the transmission line transfer capability and power system stability. PSS and FACTS devices can help the damping of power system oscillations. The objective of this paper is to design an advanced PSS and propose a systematic approach for

Robust damping control of mobile manipulators

IEEE Transactions on Systems, Man and Cybernetics, Part B (Cybernetics), 2002
A novel robust control technique, robust damping control (RDC), is introduced. An RDC controller is further developed for the motion control of a mobile manipulator subject to kinematic constraints. The knowledge of dynamic parameters of the mobile manipulator is assumed to be completely unknown.

Weakly Damped Robot Arm Control

IFAC Proceedings Volumes, 1994
A plant consisting of two rotating masses coupled with a leaf spring is driven by a dc motor. The task is to control the position of the second mass, where only its position and the motor current are measurable. It is shown that a control observer approach or PI-control based on a reconstructed signal leads to better results for the overall performance

The evolution of damp control

Journal of Building Survey, Appraisal & Valuation, 2020
Deterioration of the built environment as a result of dampness has long been considered, with evidence of this dating back to Roman times. Much of the way in which our buildings have evolved is associated with the control of moisture. In this paper we review methods to prevent issues of moisture rising into walls by capillary action, both at the ...

Structural control with dissipative damping devices

Proceedings of the 2002 American Control Conference (IEEE Cat. No.CH37301), 2002
Structural vibration mitigation using semiactive control strategies has received special attention recently due to the attractive properties of semiactive devices. The main restriction of a semiactive device is that it can only produce dissipative forces, which may be expressed in mathematical terms as a nonlinear inequality constraint. Standard active

Controllability of Damped Flexible Systems

IFAC Proceedings Volumes, 1989
Abstract Exact controllability of some damped flexible systems is developed. It is based on a generalized version of Hilbert Uniqueness Method (developed by Lions) using semigroup approach. Two second order evolution equations with damping are treated and corresponding illustrative examples are given.

Passive damping controller design for nanopositioners

2014 American Control Conference, 2014
A design of a passive damping controller to damp first resonant mode of a piezoelectric tube scanner (PTS) used in most commercial atomic force microscopes (AFMs) for nanopositioning is proposed in this paper. The stability analysis between the proposed controller and PTS is presented by an analytical framework which examines the finite-gain stability ...
