This paper focuses on the single state feedback
stabilization problem of unified chaotic system and circuit
implementation. Some stabilization conditions will
be derived via the single state feedback control scheme.
The robust performance of controlled unified chaotic systems
with uncertain parameter will be investigated based
on maximum and minimum analysis of uncertain parameter,
the robust controller which only requires information
of a state of the system is proposed and the controller is
linear. Both the unified chaotic system and the designed
controller are synthesized and implemented by an analog
electronic circuit which is simpler because only three variable
resistors are required to be adjusted. The numerical
simulation and control in MATLAB/Simulink is then provided
to show the effectiveness and feasibility of the proposed
method which is robust against some uncertainties.
The results presented in this paper improve and generalize
the corresponding results of recent works.
