Abstract
Consider a linear stochastic system with a white coefficient under a quadratic cost. Conditions are given that guarantee the superiority of the optimal controller designed on a model with an erroneous variance of the coefficient over the certainty equivalence controller and the existence of the actual cost for infinite horizon.
