The control of the open loop unstable systems with nonlinear structure is challenging work. In this paper. for the first time. we present a sand cat swarm optimization (SCSO) algorithm-based state feedback controller design for open-loop unstable systems. https://www.bekindtopets.com/hot-sale-Osborne-RN3-Big-Wheel-Nursery-Hog-Feeder-best-save/
