Abstract

Scaling the inputs and outputs of a digital controller is necessary to guarantee that these signals do not exceed the dynamic range of the analog-to-digital, and digital-to-analog converters. This paper gives two optimization problems that can be used to efficiently compute fully parametrized scaling matrices. An example that demonstrates the advantages of fully parametrized scaling over the more conventional diagonal scaling is given
