Abstract :
The stability robustness of uncertain systems designed using full and partial loop transfer recovery (LTR) is considered. A simple example illustrates that applying asymptotic LTR irrespectively of parameter uncertainty can lead to poor robustness properties. The example demonstrates the use of partial recovery to improve stability robustness while maintaining adequate estimator performance
