A nested computational approach to the discrete-time finite-horizon LQ control problem. (English) Zbl 1041.49031

Summary: A new algorithmic setting is proposed for the discrete-time finite-horizon linear-quadratic (LQ) optimal control problem with constrained or unconstrained final state, no matter whether the problem is cheap, singular, or regular. The proposed solution, based on matrix pseudoinversion, is completed and made practically implementable by a nesting procedure for welding optimal subarcs that enables arbitrary enlargement of the control time interval.
