摘　　要：采用频域Hopf定理研究了一典型卫星姿态控制系统发生Hopf分叉的条件,给出了控制器参数与Hopf分叉的关系。结果表明控制器参数在一定程度上影响着姿控系统的非线性动力学特性,控制系统综合必须全面考虑系统可能发生的分叉、混沌等复杂动力学行为。The Hopf bifurcation in a typical satellite attitude control system is studied by frequency domain Hopf theorem, and results show that the parameters of the controller have influences on the nonlinear dynamics of the whole attitude control system, and the relationship between the Hopf bifurcation and the parameters of controller is revealed. The synthesis of nonlinear control systems should study not only the local characteristics near equilibriums, but also the possible complicated dynamical behaviour such as chaos, bifurcation.
