Abstract :
The author considers an indirect adaptive unity feedback controller consisting of an mth-order SISO (single input, single output) compensator controlling an nth-order strictly proper SISO plant. It is shown that exponential convergence of the plant parameter estimation error as well as asymptotic time invariance and global exponential stability of the controlled closed-loop system can be guaranteed by requiring that the reference input has at least 2n+m points of spectral support
