Functional core-shell-structured particles have attracted considerable attention recently. This paper reviews the synthetic methods and morphologies of various electro-stimuli responsive polyaniline (PANI)-coated core-shell-type microspheres, including PANI-coated Fe 3 O 4 , SiO 2 , Fe 2 O 3 , TiO 2 , poly(methyl methacrylate), poly(glycidyl methacrylate), and polystyrene along with their electrorheological (ER) characteristics when prepared by dispersing these particles in an insulating medium. In addition to the various rheological characteristics and their analysis, such as shear stress and yield stress of their ER fluids, this paper summarizes some of the mechanisms proposed for ER fluids to further understand the responses of ER fluids to an externally applied electric field.

“…The closedloop control system with a sliding mode controller selected for the wire cut discharge machine, in order to adjust the wire tension (Kim et al, 2002).The devices used to control the tape tension contain viscous brakes with ER fluids. The brakes are also controlled with the use of the closed-loop feedback (Choi et al, 1997(Choi et al, , 2007Jun and Lamei, 2018). The advantage of this manner of control is a short control time (Kim et al, 2002;Mazursky and Tae-Heon, 2018).…”

This article concerns the identification of a transfer function which contains principal design and dynamic parameters of a hydraulic viscous disc clutch operated and controlled by an electrorheological (ER) fluid as a working fluid. A mathematical model of clutch dynamics is created as part of the clutch identification. It is considered that the changes in torque over time are described by transfer function represented by the first-order system with time delay. A prototypic clutch and a test bench are constructed, and tests are performed. A high voltage step input is used to trigger the torque changes. Constant parameters of the first-order system with time delay are identified on the basis of bench tests. According to the values of these parameters, a proportional-integral (PI) controller is selected for the closed-loop control system. It is found that operation of such a control system utilizing the identified design parameters is acceptable with high accuracy under external disturbances.

The paper presents the application of a strain gauge sensor and a viscous brake filled with an electrorheological (ER) fluid, which is a smart material with controlled rheological properties, by an electric field to the fluid domain. For experimental tests, a cylindrical viscous brake was designed. The tests were carried out on a test stand especially prepared for this purpose and suitable for the examination of the impact of the rotational speed of the input shaft and the value of the electric voltage supplied to the viscous brake on pressing forces, taking into account the ER fluid temperature and brake fluid filling level. On the basis of the experimental research results, a viscous brake control system to exert constant pressing forces with feedback from a strain gauge sensor, based on the programmable logic controller, was designed and implemented. This system, using its own control algorithm, ensured a control pressing force within the assumed range, both during the constant and follow-up control. The measurement results obtained during the tests of the viscous brake designed to exert a force were presented in the form of time courses, showing the changes of the pressing force, the electric voltage applied to the brake and the rotational speed of the brake input shaft. The developed ER fluid brake control system with feedback was tested for constant and follow-up control, taking into account the impact of the working fluid temperature. During the test it was possible to obtain a maximum pressing force equal to 50 N for an electric voltage limited to 2.5 kV. The resultant error was lower than 1 N, wherein the adjustment time after changing the desired value of the force was around 1.5 s. The correct operation of both the brake and the control system, as well as the compatibility of the pressing force value and time adjustment, were determined. The main technical contribution described in this article is the design of a new type of DECPF and a new method for its control with the use of a specifically programmed programmable logic controller which simulates the proportional-integral controllers’ operation.
