Query: Fractional-order Generalized Principle of Self-Support (FOG PSS) in
  Control Systems Design   This paper reviews research that studies the principle of self-support (PSS)
in some control systems and proposes a fractional-order generalized PSS
framework for the first time. The existing PSS approach focuses on practical
tracking problem of integer-order systems including robotic dynamics, high
precision linear motor system, multi-axis high precision positioning system
with unmeasurable variables, imprecise sensor information, uncertain parameters
and external disturbances. More generally, by formulating the fractional PSS
concept as a new generalized framework, we will focus in the possible fields on
the fractional-order control problems such as practical tracking,
$\lambda$-tracking, etc. of robot systems, multiple mobile agents, discrete
dynamical systems, time delay systems and other uncertain nonlinear systems.
Finally, the practical tracking of a first-order uncertain model of automobile
is considered as a simple example to demonstrate the efficiency of the
fractional-order generalized principle of self-support (FOGPSS) control
strategy.
