英文摘要：

In this paper, we study the amplitude control problem of limit cycle of Hopf bifurcation in a new nonlinear dynamical system. Based on the bifurcation control theory of nonlinear dynamic systems, a universal nonlinear controller is designed. By applying a specific nonlinear controller to the system, we succeed in feedbacking controlling amplitudes of limit cycle of the Hopf bifurcation. We also get the computational formula for approximately calculating amplitudes of the limit cycle. Finally, a series of numerical simulations verify the correctness of the theoretical analysis and the effectiveness of the proposed control method.
