Abstract
In this paper, we discuss a class of optimal control problems of nonsmooth systems
governed by quasi-linear elliptic partial differential equations, give the existence of the problem. Through
the smoothness and the approximation of the original problem, we get the necessary condition, which can
be considered as the Euler-Lagrange condition under quasi-linear case.
