Query: Projective synchronization in fractional order chaotic systems and its
  control   The chaotic dynamics of fractional (non-integer) order systems have begun to
attract much attention in recent years. In this paper, we study the projective
synchronization in two coupled fractional order chaotic oscillators. It is
shown that projective synchronization can also exist in coupled fractional
order chaotic systems. A simple feedback control method for controlling the
scaling factor onto a desired value is also presented.
