Robust Control and Closed-loop Identification by Normalized Coprime Factorization
نویسندگان
چکیده
This paper deals with design of a failure tolerant control system where failures are identified using the normalized coprime factorization method. The identification method employed is a closed-loop one, which is also based on coprime factorization; therefore, the method is suitable to the robust control systems. The impact of failure on the closed-loop stability is evaluated by ν-gap metric obtained from the estimated plant. To illustrate the effectiveness of the control and identification method, a simple design example and simulation results are shown.

Studies on iterative identification and model based control design have shown the necessity for identifying models on the basis of closed-loop data. Estimating models on the basis of closed-loop data requires special attention due to cross correlation of noise and input signals and the possibility to estimate unstable systems operating under a stabilizing closed-loop controller. This paper prov...

متن کاملClosed Loop Frequency Domain Identification of Fractional Model Representations using a Maximum Amplitude Criterion
An iterative scheme of identification and model based control design can be used to tackle the problem of designing an enhanced and robust control system for a plant with unknown dynamics (Schrama 1992). In such an iterative scheme, closed loop experimental conditions are indispensable to obtain data from the (possibly unstable) plant. However, by employing the knowledge of the controller used ...
