摘要

There has been considerable interest lately in the application of singular value analysis in systems theory. The basic ideas, however, were developed in statistics (Hotelling introduced principal component analysis in 1933) and are currently used in numerical analysis and digital filtering. The fundamental results underlying principal component analysis are presented in this paper, and these results are applied to the problem of tuning multivariable proportional plus integral controllers. Although the tuning method proposed is preliminary, it is designed to avoid possible traps which would prevent 'tight' tuning with conventional tuning of individual loops. When applied to non-interacting loops, the method reduces to conventional tuning of the loops simultaneously. (Author)
