MOTION CONTROL OF ELECTROMAGNETIC RECIPROCATING ACTUATOR FOR METAL BELLOWS PUMP

Miniaturization of Freon Compressor: The Bellows Pump

MINIATURIZATION OF THE FREON COMPRESSOR: THE BELLOWS PUMP James L. Kamm University of Toledo Thermal Engineering Company Toledo, Ohio All indicators point to the decade of the 1980's as the years of conservation. Whatever the technological "fix" of the future that will bring endless and sufficient energy supplies, if one exists, it will not be available within this time framework. Conservation ...

A MEMS electrochemical bellows actuator for fluid metering applications.

We present a high efficiency wireless MEMS electrochemical bellows actuator capable of rapid and repeatable delivery of boluses for fluid metering and drug delivery applications. Nafion®-coated Pt electrodes were combined with Parylene bellows filled with DI water to form the electrolysis-based actuator. The performance of actuators with several bellows configurations was compared for a range o...

A Control of an Electromagnetic Actuator Using Model Predictive Control

In permanent magnetic machines the nonlinearity due to the quadratic terms of the current makes difficulties in the control system. In order to cancel the nonlinearity, a strategy based on a pre-compensation action, which is conceived through two input partition matrices is presented. After canceling the nonlinearity a Model Predictive Control is used to obtain a positioning of the actuator. Si...

3D Force Control System Design for A Hydraulic Parallel Bellows Continuum Actuator

A self-priming, roller-free, miniature, peristaltic pump operable with a single, reciprocating actuator.

We present a design for a miniature self-priming peristaltic pump actuated with a single linear actuator, and which can be manufactured using conventional materials and methods. The pump is tolerant of bubbles and particles and can pump liquids, foams, and gases. We explore designs actuated by a motor (in depth) and a shape memory alloy (briefly); and briefly present a manually actuated version...
