A non-ideally excited pendulum controlled by SDRE technique [PDF]
Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2016 In this work, the perturbation theory is applied to the analysis of an electromechanical pendulum system. The frequency response behavior of the system is studied, and the existence of unstable poles is detected using the Routh–Hurwitz criterion. Numerical simulations show the existence of nonlinear behaviors such as hysteresis and the Sommerfeld ...
