Two main approximations are used to solve a nonlinear-quadratic-Gaussi
an (LQG) optimal control problem: the control law is assigned a given
structure in which a finite number of parameters have to be determined
to minimize the cost function (the chosen structure is that of a mult
ilayer feedforward neural network), and the control law is given a ''l
imited memory.'' The errors resulting from both assumptions are discus
sed. Simulation results show that the proposed method may constitute a
simple and effective tool for solving, to a sufficient degree of accu
racy, optimal control problems traditionally regarded as difficult one
