heal.abstract	This paper presents the linear-quadratic optimal control problem for the discrete-time descriptor systems Ex//k// plus //1 equals Ax//k plus Bu//k, where E is a singular matrix, the system structure is, in general, non-causal and its boundary conditions information is specified in terms of d initial conditions and (n-d) final conditions, where d equals deg left brace det( lambda E-A) right brace . It is shown that the optimal control law depends only on the d-dimensional state variables of the causal subsystem, and the optimal cost-to-go is a general quadratic expression of the causal state variables and does not depend on the entire descriptor vector. This result constitutes an extension to the non-causal system case of Larson et al. (1978), where the structure of the descriptor system had been assumed causal.	en
