Robust MRAC to disturbance using VS-type adaptive identifier.

It is well known that variable structure (VS)-type model reference adaptive controls (MRAC) are robust to disturbances. However, almost all conventional design schemes of VS-MRAC may cause chattering because of the switching function used in the control synthesis input. In this paper, we propose a new design scheme of MRAC which uses a VS-type adaptive identifier. This design scheme can avoid occurrence of chattering. Furthermore, this design scheme is robust to disturbances. © 1999 Scripta Technica, Electr Eng Jpn, 130(2): 80–87, 2000 [ABSTRACT FROM AUTHOR]
