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

摘要: 研究了非线性动力系统中的微分方程参数反演问题,给出了求解此类问题的信赖域算法,并对参数的灵敏度进行了详细分析,给出了数值模拟。
