Optimum linear adaptive design of dominant-type systems with large parameter variations

This paper presents a significant improvement over the hitherto available linear dominant system design techniques for guaranteeing system response within prescribed bounds, despite large plant parameter variations. Noteworthy features of the new technique are as follows. 1) The mapping of the plant parameter space into the closed-loop system space is exact and permits application to a much wider and more realistic class of problems than previously possible. 2) It is shown how the loop transmission bandwidth may be made very much smaller than in the previous designs, thus considerably extending the applicability of the dominant approach because of its drastically reduced sensitivity to internal noise.
