  Reset control is introduced to overcome limitations of linear control. A
reset controller includes a linear controller which resets some of states to
zero when their input is zero or certain non-zero values. This paper studies
the application of the fractional-order Clegg integrator (FCI) and compares its
performance with both the commonly used first order reset element (FORE) and
traditional Clegg integrator (CI). Moreover, stability of reset control systems
is generalized for the fractional-order case. Two examples are given to
illustrate the application of the stability theorem.
