In the fourth chapter , colored petri net ( cpn ) models of fbs are constructed , and through which the internal procedure of fbs and the relationship of mode and parameter status between different fbs are analyzed for preparation . in the fifth chapter , we discuss the development of function block application process 第四章介绍了一种有效的复杂系统分析模型? ?功能块的着色petri网( cpn )模型,为后面的功能块实现中的参数状态传播和模式切换部分做下技术准备。
After reviewing several smoothing algorithms for hybrid estimation , we presented a sub optimal approach to the d step fixed - lag smoothing problem for markovian switching system by applying the basic imm structure to the system with augmented system state and mode probability . the new fixed - lag smoothing 该算法将imm算法应用于系统状态和模型概率同时扩维的系统,能够实时计算模型概率平滑值,为实时判断系统模式切换提供依据,并弥补了chen算法的任意步固定滞后平滑算法的理论缺陷。
