分析了一类线性二次型最优控制问题的隐式离散格式。首先,我们证明了目标函数的最优值的O(h)阶收敛性,其中h是网格尺寸。在最优控制具有bang-bang结构的附加假设下,我们证明了离散和连续控制除了在一个测度集O(λ h)上是一致的。
We analyse an implicit discretization scheme for a class of linear-quadratic optimal control problems. First, we show convergence of order O(h) for the optimal values of the objective function, where h is the mesh size. Under the additional assumption that the optimal control has bang–bang structure we show that the discrete and the continuous controls coincide except on a set of measure O(√h).
