SERVO SYSTEM FOR CARDIAC MECHANICS EXPERIMENTS

1980
ABSTRACT A servo system was developed in our laboratory for a wide variety of cardiac mechanics experiments in dogs. The system consists of a linear-motion servo motor with a cylinder-piston arrangement designed to displace volumes as large as the cardiac stroke volume through a large bore cannula (1/2″ i.d.). The cannula is inserted through the apex

Design of Hybrid-Driven Servo Press Mechanism

Manufacturing Engineering and Materials Handling, Parts A and B, 2005
Servo presses are notably developed and studied nowadays out of their flexible ram motion. In practice, press users can advantageously utilize a single servo press to deal with different stamping operations such as blanking, drawing, coining, embossing, etc. In this paper, a hybrid-driven servo press mechanism is studied.

Dynamic Servo Control for Underactuated Mechanical Systems

Volume 4: Dynamics, Control and Uncertainty, Parts A and B, 2012
Due to the lack of control inputs, the motion range and application areas of underactuated mechanical system are greatly limited. To overcome such difficulties, the arbitrary state point dynamic tracking problem named dynamical servo control is discussed in this paper.

Constraint-following Servo Control Design for Mechanical Systems

Journal of Vibration and Control, 2009
A mechanical system is required to obey a set of constraints. The tools to accomplish this performance requirement are a set of servo controls1 that is, the servo controls are to generate the appropriate constraint force. In this article, the servo control design problem for constraint-following is thoroughly discussed. The problem is formulated as an

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.
