Abstract
In industrial processes, it is necessary to maintain the user-specified control performance in order to achieve desired productivity. This paper describes a new design scheme of performance-driven controllers in which `controller design' is fuzed with `control performance assessment'. According to the proposed scheme, control parameters are tuned by using a FRIT (Fictitious Reference Iterative Tuning). Therefore, the control performance is improved by only once using closed-loop data. The proposed scheme is a kind of data-oriented controllers whose control parameters are directly calculated without estimating system parameters. The effectiveness of the proposed method is verified by using a simulation example and experiment results.
