Abstract
This work presents two parallel asynchronous algorithms for the solution of the optimal
control problem of linear large scale dynamic systems. These algorithms are based on the
prediction concept. The first one adopts the interaction prediction approach and the second
is based upon the costate prediction approach. The convergence behavior of the proposed
algorithms is thoroughly investigated. The new algorithms are applied on three practical systems
and simulation results are presented and compared with those obtained using the well known
synchronous algorithms. It is shown that substantial saving in computation time can be achieved
by employing the proposed asynchronous algorithms.
