Costa Rica is well known for its ecological and landscape diversity. Nevertheless, most of its cities have lost their natural richness due to uncontrolled growth in infrastructure. Urban development has caused surface ...
Model reference pi controller tuning for second order inverse response and dead time processesand science
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
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. ...
Effect of Densification Conditions on Physical Properties of Pellets Made From Sawmill Residues
Sawmill residues produced in wood processing of Pilon (Hyeronimaalchorneoides) and Eucalyptus (Eucalyptus spp) species, were used to fabricate pellets with experimental design equipment. Different manufacturing conditions ...
Using the oxyhydrogen as an additive to increase the performance of an internal combustion engine
Reducing the pollution emission associated with oil combustion is gaining an increasing interest worldwide. Recently, Brown’s gas (HHO gas) has been introduced as an alternative clean source of energy. A system to generate ...
