Abstract: In this paper, inverse problems about differential equation parameters of nonlinear dynamic system have been discussed. A trust region method is proposed which can be used to solve these inverse problems. The sensitivity of parameters is analyzed in detail. The numerical simulation is given.

Key words: dynamical system, trust region, parameter estimation, differential equation, sensitivity
