Design and synthesis methods for a class of multivariable feedback control systems based on single-variable methods
E. Bohn · Transactions of the American Institute of Electrical Engineers Part II Applications and Industry · 1962
A definition of noninteraction for a class of closed-loop multivariable control systems based on a small error matrix and high loop gains is proposed. It is shown that strong cross-coupling of the open-loop system is often necessary to realize the high gains. Methods of design based on single-variable methods are developed and numerous examples discussed.
