Abstract
Scaling the inputs and outputs of a digital controller is necessary to guar antee that these signals do not exceed the dynamic range of the analog-to-d igital and digital-to-analog converters. This paper gives two optimization problems that fan be used to efficiently compute full-scaling matrices. An example that demonstrates the advantages of full scaling over the more conv entional diagonal scaling is given.
