Self-tuning control via open-loop adaptation: Pole placement approach

Research output: Contribution to journalArticleResearchpeer-review


In this paper an alternative approach is proposed for the application of Self Tuning strategies, specially those based on pole-placement. The approach is based on a special configuration for Two Degree of Freedom (2-DOF) controllers. Within this configuration, the first degree of freedom is used to close the loop and to generate a feedback system with some stability guarantees. On the other hand, the second degree of freedom, that operates in open loop, will completely determine the reference to command behaviour. This second parameter is the one that will be determined adaptively. As a special advantage of this adaptation scheme, the design block, when using a pole-placement approach, will not need to solve the usual diophantine equation. Therefore, the adaptation algorithm results computationally easier and suitable for implementation.
