Abstract: 
 In this article, we study the exact controllability of an abstract
 model described by the controlled generalized Hammerstein type
 integral equation
 $$
 x(t) = \int_0^t h(t,s)u(s)ds+ \int_0^t k(t,s,x)f(s,x(s))ds,
 \quad 0 \leq t \leq T <\infty,
 $$
 where, the state $x(t)$ lies in a Hilbert space $H$ and
 control $u(t)$ lies another Hilbert space $V$ for each time
 $t \in I=[0,T]$, $T>0$. We establish the controllability
 result under suitable assumptions on $h, k$  and $f$ using
 the monotone operator theory.
