摘要: For dynamical systems, unstable periodic motion can play an important role, such as the walking behavior for human. Due to dynamic characteristics, is difficult stay on its limit orbit or equilibrium even when small disturbance occurs. Therefore, it unusual observe motions in real world applications. At some specific circumferences, design a proper controller system properly required becomes problem be solved. In this paper, brushless motor model with unsteady external torque will investigated. The analytic bifurcation of obtained through semi-analytic approach which called discrete implicit maps algorithm. Based node points motions, solution expressed Fourier series. stable and analytical solutions verified by numerical predictions. Then feedback designed that permanently. simulation without compared show effectiveness controller.
