Polynomial Equation Approach to the Dual Criterion Stochastic Optimal
Control Problem: Application to an Extruder
In this paper a polynomial approach to the solving of dual criterion stochastic
optimal control problem for a general single-input single-output linear discrete
stochastic system is considered. The discussed optimal control problem solution
involves solving of three polynomial Diophantine equations and two polynomial
spectral factorizations resulting from the appropriate transfer-function or
polynomial system representation. The presented results are applied in procedure
of designing of the optimal control based on the model of a single-screw
extruder represented in polynomial form.
