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.

Mechanical Optimization of Servo Motor

Journal of Mechanical Design, 2005
A servo system moves a mass from one position to another as quickly as possible. A servo motor requires very high short term torque and should be able to accelerate and decelerate very quickly. In other words, a servomotor should be able to produce high torque and its inertia must be low.

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.

Nonsmooth dynamic filtering for mechanical servo-systems

2016 12th IEEE International Conference on Control and Automation (ICCA), 2016
In this paper, a nonsmooth dynamic filtering approach is proposed for stochastic noise filtering of mechanical servo-systems. In this approach, a stochastic nonsmooth state-space model with sandwich structure is developed to describe the nonsmooth dynamic feature of the system in random noisy case.

Characteristics Analysis of Working Mechanisms for Servo Mechanical Presses

Applied Mechanics and Materials, 2012
Based on analysis of press working characteristics, some of the main kinematics requirements for working mechanisms of servo mechanical presses were put forward: fast in empty stroke, slow and uniform in working stroke and big force gain. Crank link and knuckle-straight link are the most common working mechanisms in mechanical presses.

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

The servo-mechanical subsystem

1998
The CD-ROM servo electronics is basically associated with two control loops which keep the laser spot in focus on the impressed disc surface and, while playing back the recorded information, keep the laser spot following the disc spiral. In addition, the servo circuitry must also be able to find a particular location on the disc.
