Design of a performance-driven self-tuning controller via one-parameter tuning

In the challenge to manufacture high quality products it is necessary to regularly monitor performance of control loops that regulate the quality variables of interest. This paper describes a design scheme of performance-driven self-tuning controllers which are based on the above control strategy. According to the proposed control scheme, `control performance evaluation' and `controller design' can be integrated, and the desired control performance can be maintained and/or improved via only one user-specified parameter. The behavior of the proposed control scheme is numerically evaluated by a simulation example.
