A new approach to estimate the Minimum Variance Control law for Nonminimum phase Multivariable Systems

摘要

This paper introduces a new approach to calculate the minimum variance control law, which consists of a more direct and non-iterative procedure. It is based on factorization methods that preserve the directionality of nonminimum phase factors what yields a performance index closer to the actual achievable one. The proposed methodology was carried out for different case studies and compared with those obtained from a generalized interactor matrix. The results have shown the capability of the proposed methodology to yield a suitable MIMO controller performance index.
