Characterization of Limit Cycle Oscillations Induced by Fixed Threshold Samplers
IEEE (2022-06-13)In this work, a generalized study of the conditions for the appearance of limit cycle oscillations induced by any kind of sampler with multilevel fixed thresholds is presented. These kinds of samplers, which will be referred ... -
Event-based discrete PI controllers robustness analysis through sampled describing function technique
Taylor and Francis (2021-08-09)In this work, the robustness of discrete PI controllers when used with a Symmetric-Send-On-Delta (SSOD) sampling law is addressed. Hitherto, the continuous Describing Function has been employed as a suitable tool to evaluate ...

On-line retuning of PID controllers with fixed threshold samplers
Elsevier (2023-04-11)The appearance of limit cycle oscillations in control systems with fixed threshold based samplers degrades the performance of the control loop, accelerates the wear out of actuators, and introduces an unnecessary communication ...

Tuning PID controllers with Symmetric Send-on-Delta sampling strategy
Elsevier (2019-10-23)A procedure for tuning PID controllers with SSOD sampling for FOPTD systems is proposed. It is based on the definition of a new robustness measure to avoid limit cycle oscillations, called the Tsypkin margin (MT). This ...

Tuning procedure for event-based PI controllers under regular quantization with hysteresis
Elsevier (2021-04-20)In this paper a tuning procedure is proposed for event based PI controllers with Regular Quantization with Hysteresis (RQH) sampling law. The RQH is a generalization of Symmetric Send on Delta (SSOD) strategy which decreases ...
