A NEW METHOD OF THE WEIGHTED MATRIX SELECTION IN THE OPTIMAL STATEFEEDBACK DESIGN──ZERO ADDITION DECOUPLE DESIGN METHOD

In the optimal control system design,as the relation between quadratic evaluation functionand the close-loop system is unknown, heuristic method is often used to select the weighted matrix Q,R. Itnot only makes the amount of work increase, but also makes the control system alignment at the workplacebe very difficult. This paper states a new method-zero addition decouple design method to select the weightedmatrix Q,R.
