Static Compensator for Decentralized Control of Nonsquare Systems

Abstract

The paper deals with the decentralized control problem for linear multivariable systems with the number of manipulated variables equal or greater than the number of controlled variables. Proposed static compensator ensures automatic creation of input/output pairs for individual control loops. The compensator provides steady state autonomy and unit gain for the control loops. Steady state gain matrix of the controlled system and vector of offsets are sufficient infor-mation for the compensator design. Estimation of the gain matrix and offsets from the measured data is also proposed in the paper.
