Design of closed-loop control for generation of nonlinear oscillations

In this paper we present a new approach to closed-loop control design which provides generation of regular or chaotic oscillations in a dynamic systems. Proposed approach is based on idea of introduction of desired attractor (boundary circle or strange attractor) in closed-loop system state space. The practical usage of this approach for the problem of nonlinear oscillations generation in DC electromechanical system is shown.
