Abstract
In this paper, the conceipt of one-way interacting control of linear multivariable systems is proposed and its general design procedure is studied. The control system is called “one-way interacting”, when its closed loop transfer matrix is a triangular one.
Both the transfer function approach and the state space approach are employed to analyze the system, and the necessary and sufficient conditions for the one-way interacting control are given.
The merit of this system is that more parameters can be used to design its controllers than the conventional non-interacting control system. It is also pointed out the characteristic equation of the stability criteria can be calculated for each controlled variable independently.
A comparative example illustrates that one-way interacting control works better with simpler controllers than the non-interacting ones.
