The problem of minimizing a weighted sum of the input and output variances from a linear scalar system is considered. This is viewed as an optimization problem with the parameters of the regulator as unknowns and it is proved that if the regulator is flexible enough, then every local minimum to this problem is a global optimum. This result is useful if a gradient method is used to find the optimal regulator.
