PID Control in the Third Millennium
Control loop performance assessment and improvement of an industrial hydrotreating unit and its economical benefits. Longhi I ; A. Reginato I ; H. Teixeira II ; C. Cortez II ; L. Lusa III ; S.
The early 21 st century has seen a renewed interest in research in the widely-adopted proportional-integral-derivative PID controllers. Each chapter has specialist authorship and ideas clearly characterized from both academic and industrial viewpoints. Advances in Industrial Control aims to report and encourage the transfer of technology in control engineering. The rapid development of control technology has an impact on all areas of the control discipline. The series offers an opportunity for researchers to present an extended exposition of new work in all aspects of industrial control.
loops, the overall process performance and the ability to by-step process for control loop tuning. In a control loop, the controller manipulates the process.
Advanced Methods of PID Controller Tuning for Specified Performance
A proportional—integral—derivative controller PID controller or three-term controller is a control loop mechanism employing feedback that is widely used in industrial control systems and a variety of other applications requiring continuously modulated control. In practical terms it automatically applies an accurate and responsive correction to a control function. An everyday example is the cruise control on a car, where ascending a hill would lower speed if only constant engine power were applied. The controller's PID algorithm restores the measured speed to the desired speed with minimal delay and overshoot by increasing the power output of the engine. The first theoretical analysis and practical application was in the field of automatic steering systems for ships, developed from the early s onwards.

the Negative Consequences of Poor PID Controller Tuning
Much has been written about the benefits of robust PID control. Increased productivity, decreased equipment strain, and increased process safety are some of the advantages touted of proper PID tuning. What is often overlooked, though, are the negative consequences of poor PID controller tuning. If a well-tuned system helps equipment run longer and safer, then a poorly tuned system may increased failure frequency and safety incidents. The instrumentation professional should be mindful of this dichotomy when proceeding to tune a PID control system.

Фонтейна это позабавило. - Вы знаете, кто. - Какая разница? - огрызнулся светловолосый.
Анализ затрат на единицу продукции. - Мидж торопливо пересказала все, что они обнаружили с Бринкерхоффом.
Мы позвонили! - не сдавалась Мидж. - Он сказал, что у них все в порядке. Фонтейн стоял, тяжело дыша. - У нас нет причин ему не верить. - Это прозвучало как сигнал к окончанию разговора.
