Active and Semi-Active Control of Electrorheological Fluid Devices
This paper is devoted to two different applications of electrorheological (ER) fluid devices. The first application deals with the modeling and nonlinear control of an active actuator consisting of a double-rod cylinder and four ER valves arranged in a full bridge configuration. Secondly, a semi-active shock absorber system is designed by utilizing the special properties of ER valves. The latter application is also intended to demonstrate the benefits of a mechatronic design approach, where the control strategy and the system components are designed simultaneously. Measurement results prove the feasibility of the proposed ER devices.
