Design of Multivariable Control Systems by Decoupling Method of the V-Norm Type

As for multivariable plants described by the usual P-norm type, it is simpler to decouple plants with a decoupling part of the V-norm type, but it is possible that the decoupling part may be unstable. This paper pro-poses the design method of decoupling some variables of a plant with a decoupling part of the V-norm type before the plant and others with another decoupling part of the V-norm type behind plant, to obtain a complete decoupled system as much as possible in condition of the open-loop system stable. Concerning the 3-input and 3-output ball mill system of a power plant, the decoupling control system is designed and its simulation result shown.
