Fractional-order signal processing using a polymer-electrolyte transistor

Fractional-order systems have applications in the areas of flight control, robotics, missile guidance, control of structural vibrations of space platforms and sensor technology. Fractional-order transfer functions can characterize complex nonlinear dynamics with many fewer parameters than integer-order functions. This paper addresses the use of a polymer-electrolyte transistor (PET) for use in implementating fractional-order algorithms for signal processing. The PETpsilas advantage over the conventional RC and RL circuits is that it can be both functionally scaled and varied for dynamic fractional-order parameter controllability.
