摘要

An additional inner-feedback loop is used to reduce the channel interaction of a multivariable control system such that the design of the outer-feedback loop can be treated as a single-variable problem for ease in achieving the required main-channel performance. The relative error between the exact input-output relation t/sub ii/(j/spl omega/) of channel i and its approximation t/spl circ//sub ii/(j/spl omega/)={l/sub i/(j/spl omega/)f/sub ii/(j/spl omega/)}/{1+l/sub i/(j/spl omega/)} is introduced to provide an effective measure for assessing the achieved noninteraction. According to the approach proposed, the single-input/single-output quantitative-feedback-theory design method can be applied directly for the design of both inner- and outer-feedback loops.
