Robust pole placement direct adaptive control. (English) Zbl 0666.93084
This note presents a pole placement direct adaptive control for not necessarily minimum phase plants, which is robust with respect to unmodeled dynamics and bounded disturbances. The robustness is achieved by using both a normalized least-squares algorithm with dead zone and an appropriate nonlinear feedback. The resulting closed-loop system is shown to be globally stable subject to standard assumptions.
