| Abstract: | A new adaptive control scheme is proposed for multivariable MRAC systems based on the nonlinear backstepping approach in vector form. The assumption on a prior knowledge of the high frequency gain matrix in the existing results is weakened and can be easily checked for certain plants so that the proposed method is widely applicable. This control scheme guarantees the global stability of the closed-loop system and makes the tracking error tend to be zero and quadratically integrable. |
