Robust PI/PID controllers for load disturbance based on direct synthesis
(2018-10)
It is recognized that disturbance rejection is much more important than set-point tracking for many process control applications, leading set-point tracking to a secondary level of interest. In this paper a proposal for ...
I-PD controller as an structural alternative to servo/regulation tradeoff tuning
(2018)
One of the recurrent topics in the PI/PID literature of recent years is the incorporation of the tradeoff between the two possible modes of closed-loop operation: servo and regulation. Tuning rules are usually provided as ...
Improvement of the Control System Performance based on Fractional-Order PID Controllers and Models with Robustness Considerations
(2018)
In this paper we assess the performance improvement achievable by using onedegree-of-freedom fractional-order proportional-integral-derivative controllers (FOPI/FOPID) instead of their integer-order counterparts (PI/PID). ...
