We investigate the implicit Euler discretization for linear-quadratic optimal control problems with index two DAEs. There is a discrepancy between the necessary conditions of problems with higher index DAEs and their discretizations, since the necessary conditions of the continuous problem coincide with the necessary conditions of the index reduced problem. This implicit index reduction does not occur for the discretized problem. Thus, the respective switching functions cannot be related. The discrepancy is overcome by reformulating the discretized problem, which yields an approximation of the index reduced problem with suitable necessary conditions. If the switching function has a certain structure, such that the optimal control is of bang–bang type, we can show that the controls converge with an order ofin theL1-norm. We then improve these error estimates with slightly stronger smoothness conditions of the problems data and switching function, which gives us a convergence order of one.
