摘要: This note deals with the design of reduced-order disturbance decoupled scalar functional observers for linear systems unknown inputs. Based on a parametric approach, existence conditions are derived and procedure finding is given. The relaxed can find first-order some cases where number inputs more than outputs. Also, observer matching condition, which necessary requirement state inputs, not required. Numerical examples given to illustrate attractiveness proposed method.
