Simple Transform Method of Algebra Equivalent Observer for Higher-order Inertial Element

For the rapid calculation of what the parameters of AEO having effect on the control system,based on the actual application of the algebra equivalent observer of higher-order inertial element,and according to the matrix of standard type of the Jordan's,a matrix block JBS of Jordan standard type in board sense is defined.A simple calculation method of the transform matrix P is given by mathematical analysis.So an effective method for open out the inherent relation of algebra equivalent observer is presented.This method not only helps to designing of the regulative system,but also can achieve a more beneficial effect by using appropriately.The practicality and validity of the method proposed is testified by an application case of 600 MW unit's boiler super-heater steam temperature control system in a power plant.
