Model reference pi controller tuning for second order inverse response and dead time processesand science
(2016-09-06)
In this paper, a One-Degree-of-Freedom PI controller is optimized using the model reference tuning approach for a Second Order Inverse Response and Dead Time Process operating as a servo control. In addition, a graphic ...
Improved PID controller tuning rules for performance degradation/robustness increase trade-off
(2016-09)
Definitely, robustness is an important feature that any control system must take into account, especially considering that the design is usually based on low-order linear models that represent the whole controlled process. ...

equipment. Different manufacturing conditions ...
Does elevation influence the distributional patterns of tropical myxomycetes? A case study in Costa Rica
(2016)
In order to test the hypothesis that elevation may be an important factor accounting for the
distribution of myxomycetes in tropical forests, this project was designed and conducted in Costa
Rica. Two lower elevational ...
