Abstract
A two-stage process is proposed for the design of low-sensitivity constant gain feedback linear regulators. In the first stage nominal parameter values are assumed and a model response is obtained. Plant parameter variations are taken into account in the second stage, and a sensitivity reduction algorithm is described in which a performance index which includes a model-following term is to be minimized. The computer solution of the feedback matrix is obtained using a gradient search method, and a fourth-order aircraft flight control example illustrates the design's capabilities.
