Set Point and Identifiability in the Closed Loop with Minimum Variance Controller

Set Point and Identifiability in the Closed Loop with a Minimum-variance Controller

The meaning of nonzero set points for the identiiability of the AR-MAX model parameters in a closed-loop system with a minimum-variance controller is explained and discussed. It is pointed out that, in the case of a zero set point and an ARMAX model resulting from the discretization of a continuous-time plant, the model parameters cannot be identiied in a closed-loop system with a minimum-varia...

Closed-Loop Controller Design

Closed-loop controllers use outputs of the system to improve overall stability and increase tolerance against external disturbances. The latter makes it possible to control inherently unstable systems. As expected, there are some important differences from open-loop controllers. Most importantly, we must distinguish between measurable outputs of the system and the properties we really want to c...

Identifiability of Linear Closed-loop Systems

Identifiability of MIMO linear dynamic systems operating in closed loop

Identification of multi-input muiti-output [MIMO) Section 3 of the naner is concerned with the case -~~~ ~-. ~-~~r ~ ~ r ~ ------.---~~ ~ ~ ..~.. linear dynamic systems is considered for the c&e when the measurements are obtained during closed loop operation. Both where the disturbances in the feedback path are a noise free and noisv feedback situations are analvsed. For the full rank stochasti...
