Many fractional models can be represented by the following system

in a Banach space *X*, where 0 < *α* ≤ 1, *t* ∈ [0, *a*], *u*
_{0} ∈ *X*, *i* = 1, 2,..., *m* and 0 < *t*
_{1} < *t*
_{2} < ··· < *t*
_{
m
} < *a*. We assume that -*A*(*t*,.) is a closed linear operator defined on a dense domain *D*(*A*) in *X* into *X* such that *D*(*A*) is independent of *t*. It is assumed also that -*A*(*t*,.) generates an evolution operator in the Banach space *X*. The functions *f* : *J* *X*
^{
r+1}→ *X*, *g* : Λ × X^{
k+1}→ *X*, *h* : *PC*(*J*, *X*) → *X*, *u*(*β*) = (*u*(*β*
_{1}),..., *u*(*β*
_{
r
})), *u*(*γ*) = (*u*(*γ*
_{1}),..., *u*(*γ*
_{
k
})), and *β*
_{
p
}, *γ*
_{
q
}: *J* → *J* are given, where *p* = 1, 2,..., *r* and *q* = 1, 2,..., k. Here *J* = [0, *a*] and Λ = {(*t*, *s*). 0 ≤ *s* ≤ *t* ≤ *a*}. Let *PC* (*J*, *X*) consist of functions *u* from *J* into *X*, such that *u*(*t*) is continuous at *t* ≠ *t*
_{
i
}and left continuous at *t* = *t*
_{
i
}and the right limit
exists for *i* = 1, 2,..., *m*. Clearly *PC*(*J*, *X*) is a Banach space with the norm ||*u*||_{
PC
}= sup_{
t∈J
}||*u*(*t*)||, and let
constitutes an impulsive condition. Fractional differential equations have proved to be valuable tools in the modelling of many phenomena in various fields of science and engineering. Indeed, we can find numerous applications in viscoelasticity, electrochemistry, control, porous media, electromagnetic, etc. (see [1–5]). They involve a wide area of applications by bringing into a broader paradigm concepts of physics and mathematics [6–8]. There has been a significant development in fractional differential and partial differential equations in recent years, see Kilbas et al. [9, 10], also in fractional nonlinear systems with delay and fractional variational principles with delay, see Baleanu et al. [11, 12].

The existence results to evolution equations with nonlocal conditions in Banach space was studied first by Byszewski [

13,

14], subsequently, many authors were pointed in the same field, see reference therein. Deng [

15] indicated that, using the nonlocal condition

*u*(0) +

*h*(

*u*) =

*u*
_{0} to describe for instance, the diffusion phenomenon of a small amount of gas in a transparent tube can give better result than using the usual local Cauchy problem

*u*(0) =

*u*
_{0}. Let us observe also that since Deng's papers, the function

*h* is considered

where *c*
_{
k
} , *k* = 1, 2,..., *p* are given constants and 0 ≤ *t*
_{1} < ··· < *t*
_{
p
} ≤ *a*. However, among the previous research on nonlocal cauchy problems, few are concerned with mild solutions of fractional semilinear differential equations, see Mophou and N'Guérékata [16], and others with fractional nonlocal boundary value problems, for instance, Ahmad et al. [17, 18].

The theory of impulsive differential equations has been emerging as an important area of investigation in recent years, because all the structures of its emergence have deep physical background and realistic mathematical model. The theory of impulsive differential equations appears as a natural description of several real processes subject to certain perturbations whose duration is negligible in comparison with the duration of the process. It has seen considerable development in the last decade, see the monographs of Bainov and Simeonov [19], Lakshmikantham et al. [20], and Samoilenko and Perestyuk [21] where numerous properties of their solutions are studied, and detailed bibliographies are given.

Recently, the existence of solutions of fractional abstract differential equations with nonlocal initial condition was investigated by N'Guérékata [22] and Li [23]. Much attention has been paid to existence results for the impulsive differential and integrodifferential equations of fractional order in abstract spaces, see Benchohra et al. [2, 24]. Several authors have studied the existence of solutions of abstract quasilinear evolution equations in Banach space [25–27].

Regarding this article, it generalizes previous results concerned the existence of solutions to nonlocal and impulsive integrodifferential equations of quasilinear type with delays of arbitrary orders. Section "Preliminaries" is devoted to a review of some essential results. In next section, we state and prove our main results, the last section deals to giving an example to illustrate the abstract results.
