A Frequency-Domain Stability Method for Reset Systems | | Ali Ahmadi Dastjerdi

6 May 2020 | | Abstract: | Nowadays, the demand for an alternative to linear PID controllers has
increased because of the rising expectations of the high-precision industry.
The potential of reset controllers to solve this important challenge has been
extensively demonstrated in the literature. However, similarly to other
non-linear controllers, the stability analysis for these controllers is complex
and relies on parametric models of the systems which may hinder the
applicability of these controllers in industry. The well-known Hbeta method
tries to solve this significant issue. However, assessing the H{eta}
condition in the frequency-domain is complex, especially for high dimensional
plants. In addition, it cannot be used to assess UBIBS stability of reset
control systems in the case of reseting to non-zero values. These problems have
been solved in this paper for the first order reset elements, and an
easy-to-use frequency approach for assessing stability of reset control systems
is proposed. The effectiveness of the proposed approach is demonstrated through
a practical example. | | Source: | arXiv, 2005.2887 | | Services: | Forum | Review | PDF | Favorites | |
