Construction of linear plant modal control system based on discrete identification model

A modal control method based on discrete identification model was proposed in order to resolve interior uncertainty of actual control plant. The modal control method for linear discrete plant of complete state vector information was studied by using discrete standard binominal as system standard eigenequation. A methodology constructing modal control system of linear plant based on discrete identification model was proposed. Analysis results which eigenroot parameters influenced on system performance were given. The method characters are that it is easy to constructing and engineering implementing.
