| 摘 要： | 本文基于方块脉冲函数理论，分析了脉宽调制系统的精确方法，给出了便于计算机求解的递推算式，将ＬＱＰ（线性二次型问题）最优控制问题转化为求解多元函数最优化问题，避开了Ｒｉｃｃａｔｉ方程的求解，得到了状态反馈形式的分段综合控制表示式，以及最优控制的分段恒定解和最优状态轨线。

| Abstract: | Based on the block-pulse function theory,the control systems with PWM amplifier are analysed, the recursive formulas suitable for computer calculation are proposed,with which the problem of optimal control on LQP can be tranformed into the optimal solution to multiple function,so that riccati equation may be avoided.At the end the expression of pieeewise synthetic control with state feedback,the pieeewise constant solution to optimal control and optimal state tra- jectory are obtained. |
