Adaptive friction compensation of servo mechanisms

International Journal of Systems Science, 2001
In this paper, adaptive friction compensation is investigated using both model-based and neural network (non-model-based) parametrization techniques. After a comprehensive list of commonly used models for friction is presented, model-based and non-modelbased adaptive friction controllers are developed with guaranteed closed-loop stability.

Analysis of a Sampling Servo Mechanism

Journal of Applied Physics, 1950
An analysis of a sampling servo mechanism with an error-clamping device and linear forward and return paths is given. The method leads to a determination of the continuous output of the system in terms of quadratures and gives explicitly the value of the output at the discrete sampling instants.

Modeling and Control of a Servo Mechanical Press

2018 IEEE Conference on Control Technology and Applications (CCTA), 2018
The paper discusses the modeling and control of a 800 metric tons servo mechanical forming press. The control objective is to actuate the kinetic energy recovery system so to minimize the amplitude of the oscillations on the Direct Current bus line. The paper describes and models all the components of the system from an energy standpoint. Measured data

A servo-mechanical bladder dynamic simulator

Physiological Measurement, 2001
A method is described for the physical simulation of the dynamic behaviour of the urinary bladder. It has been found that the model can be controlled to an arbitrary pressure-volume characteristic essentially independent of the properties of the bladder material.

Phase Lead for A.C. Servo Mechanisms

Journal of Applied Physics, 1949
General design curves for use of lead networks on log-db plots are given. A variety of parallel and bridge T networks along with d.c. networks are evaluated for use in a.c. servo mechanisms. The restrictions existing on some networks are enumerated, and suggestions on general design procedure are made.

Positional servo-mechanism activated by artificial muscles

Medical & Biological Engineering, 1969
A positional servo-mechanism was designed to facilitate multi-layer electronic control of complex orthotic and prosthetic devices. The design aim was to obtain adequate performance of the system using lightweight, flexible and inexpensive components. The mechanism is actuated by an antagonistic pair of McKibben pneumatic muscles.

Servoing Mechanisms for Peg-In-Hole Assembly Operations

2001
Image-based effector servoing is a process of perception-action cycles for handling a robot effector under continual visual feedback. Apart from the primary goal of manipulating objects we apply servoing mechanisms also for determining camera features, e.g. the optical axes of cameras, and for actively changing the view, e.g.

Dynamics of dual-drive servo mechanism

ISIE 2001. 2001 IEEE International Symposium on Industrial Electronics Proceedings (Cat. No.01TH8570), 2002
Gantry mechanisms are widely used for precision manufacturing and material handling in electronics, nuclear, and automotive industries. A dual drive servo mechanism is a way to increase control bandwidth, in which two primary axes aligned in parallel are synchronously driven by identical servo motors.

Dynamic Model of Servo Mechanical Press

2020
Servo mechanical press is a mechatronic system, consisting of a reducer, actuator and a servomotor with a controller. Control of the servo mechanical press is carried out with a help of the controller depending of technological process of pressing. Reverse kinematic analysis of the actuator of the servo mechanical press is presented in the work to ...

The use of servo mechanisms in aircraft

Journal of the Institution of Electrical Engineers - Part I: General, 1947
In each field in which servo mechanisms have been applied in aircraft, different designers have used different mechanisms to achieve the same result, and each particular type of mechanism has been used for different applications. Therefore, this survey can show no more than a few cross-sections. Section 1 gives a brief account of the conditions which a
