Abstract A technique for the approximate decoupling of a class of non‐linear stochastic systems which has parameter variation in the plant is presented. First, nominal decoupling is obtained. Then a sensitivity model representing the plant variation is formulated and incorporated into a performance index. Minimization of this index with respect to the free parameters in the feedback matrix results in a robust feedback controller which can reduce the effect of noise and perturbations on the output. An example demonstrating the feasibility of the approach for practical problems is presented.
