Improved design scheme of MRAC for electro-pneumatic servo system with additive external forces

This paper presents an improved design scheme of MRAC for the electropneumatic servo system with additive external forces. In this design scheme, a difference process of the identification signals is adopted in the identification mechanism to eliminate the influence of the constant disturbances caused by the additive external forces. Furthermore, the controller of this design scheme is constructed with a compensator to overcome the influence of the disturbances. As a result, it can be possible to accomplish the satisfactory control performance.
