    Comparison of a Triple Inverted Pendulum Stabilization Using Optimal Control Technique.Mustefa Jibril, Messay Tadse & Eliyas Alemayehu - 2020 - In Preprints. pp. 10.
    In this paper, modelling design and analysis of a triple inverted pendulum have been done using Matlab/Script toolbox. Since a triple inverted pendulum is highly nonlinear, strongly unstable without using feedback control system. In this paper an optimal control method means a linear quadratic regulator and pole placement controllers are used to stabilize the triple inverted pendulum upside. The impulse response simulation of the open loop system shows us that the pendulum is unstable. The comparison of the closed loop impulse (...)
