Abstract :
In this paper, a robust adaptive control algorithm based on Krstic et al. (1994) new adaptive scheme is proposed by introducing auxiliary errors for plants with unmodeled dynamics and/or unmeasurable output disturbances. The use of auxiliary errors means we have made use of more information about the closed loop system and thus improve the transient performance
