# Control system defined by some integral operator

Marek Majewski

Abstract. In the paper we consider a nonlinear control system governed by the Volterra integral operator. Using a version of the global implicit function theorem we prove that the control system under consideration is well-posed and robust, i.e. for any admissible control $$u$$ there exists a uniquely defined trajectory $$x_{u}$$ which continuously depends on control $$u$$ and the operator $$u\mapsto x_{u}$$ is continuously differentiable. The novelty of this paper is, among others, the application of the Bielecki norm in the space of solutions which allows us to weaken standard assumptions.

Keywords: Volterra equation, implicit function theorem, sensitivity.
