Outline of Final Research Achievements

This project aims at solving the robust performance design problem of uncertain systems. The following outcomes are obtained:
1. We succeeded in establishing a design theory of robust performance for the systems with positive real uncertainty. 2. We succeeded in establishing a design theory of robust performance for the systems with negative imaginary uncertainty. 3. Besides the uncertainty phase property characterized by the positive realness or negative imaginariness, we succeeded in incorporating the frequency-dependent gain bound into the uncertainty model and establishing the associated design theory of robust performance for these classes of uncertain systems. 4. These methods enable high performance control design for a large class of practical systems.
Applications to real systems validate that a significant improvement of robust performance can be achieved as compared with conventional methods which only use the uncertainty gain.
