This   work   deals    with    the  problem   of   dynamic  state   estimator  for     a     class     of     non- linear    singular    dynamic    systems.  Sufficient  conditions   for  the  existence   of   such   observers   are   provided   and   the   design   of   such  observer  is examined.Since   our   nonlinear   dynamic   system   is   singular   and   assuming   that     the    singular     matrix      is      full      row     rank      involves    many   calculation         simplifications;     therefore     special     emphasis     in     the computational  aspect   of   the  observer   matrices   is    discussed   supported  by  some  useful  comments.In  this  work,  scheme    and    procedure  work    for  nonlinear  dynamical  observer  control   system  are  proposed   and  developed  to  estimate  the  unmeasured  state  space  points.The proofs  of  the theorems of this scheme as well as their computational algorithm have been developed and presented. The  concluding and necessary  remarks and  lemmas  have  also  been  discussed.Finally,  several  problems  are  given  to  demonstrate  the  validity  and   the  effectiveness    of    present  work  before  and  after their behaviors  are  simulated   and  are   shown  in  graphs.
