摘    要:本文针对具有Hammerstein模型的非线性控制系统,提出了一种确定次优稳态工况的实用新方法—改进两步法.该方法利用动态与稳态数据辨识和更新稳态模型,因而得到的解更近于实际最优解.针对线性二次型优化问题,本文还给出了改进两步法的收敛性证明,最终数字仿真结果显示了该方法的有效性.

关 键 词:改进两步法  稳态模型

Abstract:An improved two-step approach to determining the suboptimum steady-state operating conditions of Hammerstein model nonlinear system is presented. It utilizes both the dynamic information and the steady -state data to identify and improve the steady -state model. Hence,the suboptimal solution obtained by it is better than that by the standard two - step approach. This paper also gives the convergence proof of new approach for linear-quadratic system. Finally,simulation results show that the new approach is very efficient.
Keywords:improved two-step approach   steady-state model
