Reduced Active Element Power-Law Proportional-Integral Controller Designs

Abstract

Topologies of power-law proportional-integral controllers, which offer minimization of the active component count are presented in this work. This is achieved thanks to the utilization of RC networks, which approximate driving-point impedances described by power-law functions. Additional important features of the presented schemes are their capability of achieving minimization of the spread of passive elements, as well as of implementing values of order greater than one.
