Power-Mechanism Characteristic Analysis of a Symmetric Magnetorheological Pneumatic Cylinder

Magnetorheological pneumatic control technology is a kind of new technology that can overcome the disadvantages of traditional pneumatic servo system and achieve accurate and robust control. It is a new field with vast vistas. Based on the theory of magnetorheological pneumatic control technology, a magnetorheological dissymmetric pneumatic cylinder is constructed and its mathematic model is built in this paper. Capability simulink analysis of the new power mechanism is carried out by using MATLAB soft. Also the dynamic and static capabilities are compared between the new power mechanism and the traditional one. The results indicate that the new power mechanism has better dynamic and static capabilities then the traditional one. The conclusion provides a theoretical basis for the magnetorheological technology applying in the area of pneumatic technology.
