Closed Loop Output Error Structure

In this structure the plant B/A is controlled by an RST Controller . The closed loop output error is the difference between the output of the real closed loop system (controller + real plant) and the output of the closed loop predictor (controller + adjustable model plant).

u(t) : plant input

y(t): plant output

w(t): non-modeled output disturbance independent from r(t)

r(t): excitation signal

û(t): input of the adjustable plant model

ybar(t): output of the predictor

e(t): prediction error

For this structure three different algorithms can be considered: CLOE , FCLOE and AFCLOE .

In this structure the noise model is not identified. An ARMAX model for the plant is considered in Extended Closed Loop Output Error Structure .
