摘要
对非线性时滞离散动态系统的最优控制,提出了一种信息融合估计(information fusion estimation,IFE)方法,把非线性控制问题的所有信息转化为关于控制量的"测量信息",从而使非线性控制问题转化为关于控制量的"非线性估计"问题.通过算例表明,IFE方法明显优于动态系统优化与参数估计的集成(dynamic integrated system optimization and parameter estimation,DISOPE)方法.
An information-fusion estimation （IFE） method is proposed for the optimal control of time-delay nonlinear discrete-systems. All information about the control variable, including the ideal control strategy, the expected object trajectory, and the system dynamic equations are considered as the ＂measurement information＂ of the control variable. Thus, the problem of optimal control is transformed into the ＂non-linear estimation＂ problem of the control variable. The mathematical simulation results show that the IFE method is better than the DISOPE （dynamic integrated system optimization and parameter estimation） method proposed in [3].
