Feedback control for linear discrete-time systems with time delays. (English) Zbl 0559.93051
A new decomposition-coordination approach is presented to design control laws for linear discrete-time systems with distributed lags. By a proper decomposition of the criterion, one obtained a control law with partial feedback and an open loop part in order to satisfy the optimality conditions. On-line implementation of such a law is discussed and comparative examples are given to show the advantage brought by this method.
