STWS(Single-term Walsh Series)方法是 G.P.Rao 等人于1980年提出的。此文叙述了作者在前人工作的基础上,提出了把 STWS 方法与并联预估原理有机结合‘求解时变动态大系统最优控制的新方法,得到了易在微机上实现的显式递阶递推算法。该算法具有计算简单、收敛快、便于应用等优点。与 Walsh 函数和方块脉冲函数分析方法相比,该方法不但能给出分段恒定解答,而且还能给出各节点上的逼近值,从而为大系统实时优
The STWS (Single-term Walsh Series) method was proposed by G.P. Rao et al. This paper describes the author based on the previous work, put forward the STWS method combined with the principle of parallel estimates of the time-varying dynamic system optimal control of the new method is easy to achieve in the microcomputer explicit delivery Order recursive algorithm. The algorithm has the advantages of simple calculation, fast convergence, easy application and so on. Compared with Walsh function and square pulse function analysis method, this method can not only give the piecewise constant solution, but also give the approximation value of each node,
