This international journal covers the application of control theory, operations research, computer science and engineering principles to the solution of process control problems. In addition to the traditional chemical processing and manufacturing applications, the scope of process control problems involves
Process control systems monitor industrial processes to make sure they don't vary from pre-set limits. They start corrective action if they find unwanted deviations or abnormalities. The key element of a process control system is the basic closed-loop control. Systems usually include many hundreds of individual control loops, each of which controls one aspect of a particular process - for example, the temperature of an oven. The control loop's job is to make sure that a particular variable or parameter is maintained at its pre-set value, or 'set-point', and doesn't vary from this by more than an acceptable amount. The control loop must also react quickly to any changes in set-point so that production isn't interrupted. To achieve this, a control loop is made up of three main components - the measurement device, the controller and the regulator.

The performance of your process control system may gradually decline over time because your operators override the system, or your equipment and plant develop faults. You may not be aware that the system is performing badly because maintenance schedules don't always include the right checks to identify problems. If your system is poorly-maintained, your processes won't be operating efficiently and your energy costs will be higher than necessary.
Так и есть, примерно через каждые двадцать строк появляется произвольный набор четырех знаков. Сьюзан пробежала все их глазами. PFEE SESN RETM - Альфа-группы из четырех знаков, - задумчиво проговорила Сьюзан. - И частью программы они явно не являются.
По-видимому, ее работу прочел не только научный руководитель, потому что вскоре последовал телефонный звонок, а затем по почте ей доставили авиационный билет от АНБ.
