| Abstract: | A class of three degrees of freedom strongly nonlinear dynamical system is simplified by the center manifold theory, its stability and bifurcation characters are discussed. The bifurcation diagram and Lyapunov exponent graphs are simulated by Matlab. The impact of stability and bifurcation of system is studied based on different parameters, which plays a reference role for the design and production of permanent magnet synchronous motor. |
