A NEW APPROACH TO THE SENSITIVITY PROBLEM IN MULTIVARIABLE FEEDBACK SYSTEM DESIGN,
Abstract
A new point of view for the parameter variation problem in linear multivariable systems is proposed. The output deviations due to parameter variations for an open loop realization are re lated by a sensitivity matrix to the output deviations due to parameter variations for a closed loop (feedback) realization. By means of a performance index involving this sensi tivity matrix, conditions are obtained for in suring that the feedback realization is lesrealization. By means of a performance index involving this sensi tivity matrix, conditions are obtained for in suring that the feedback realization is less affected by parameter variations than an open loop realization having the same nominal transfer characteristics. A procedure based on this new sensitivity formulation is given for designing a multivariable feedback system. (Author)
