In a continuous type of process control, the physical system will be shown through variables and it will be smooth and uninterrupted in time. Mostly this type of control is used for chemical and oil industries. By using this type of process control very large quantities of products can be produced. In this type of …

The computer process control can be described as controlling a manufacturing process with the help of a digital computer. The automated system is operating by using a computer, the computer process control is specifically related to the continuous or semi-continuous operations. The computer process control is mostly related to chemicals, petroleum, food, etc. The computer …
Adaptive control can be described as an auto-correcting form of control, it is composed of both feedback and optimal control. An adaptive control system would measure the output process variable and this will be used to control the speed. So basically an adaptive control system can adjust its parameters automatically in a way to compensate …
A variable speed drive can control the speed of equipment or a process and by using a variable speed drive we can operate the process or equipment at the required speed. We can see VSD’s in many industrial applications, the assembly lines would require to operate at different speeds and it can be accomplished by …
What is a variable speed drive and why are they used in the industrial process? Read More »
The final control element would make the required changes in the manipulated variables and this variable will satisfy the requirements. In a control system the selection of the proper control element and also the selection of control element, location is an important factor. We can describe the final control element as a component in a …

A zero-speed switch is used in conveyors, motors, and it is also used to detect the rotating shaft speed. A zero-speed switch is used in conveyor belts and it would stop the conveyor if the speed of the belt falls below the set speed. These switches would trip the motor circuit if the motor is …
What is a switch A switch is used to open or close an electric circuit, a switch can break an electric circuit. The switches are called binary devices because they are either completely open or completely closed. We can see different types of switches used to do an industrial process. These switches are the major …
Automation is the technology that uses many control systems to control the equipment in a factory or in other places. There are various control systems used to do the automation they are PLC, numerical control, and industrial control system. These control systems are combined with certain computer-aided technologies so that industrial process control can be …
What is a real time system? A real-time system is a system that would produce a proper response within a definite time limit. If the controller response is exceeded beyond these time limits then it would affect the process output. Basically, real-time is a measured value by using a real clock, a real-time system would …

In this control system, certain actions will be performed during an event, an example of this will be closing a valve if the liquid level reaches a predetermined value. The major use of an event-based controller is in alarm indications like if the pressure or temperature level is too high. The event based controller would …
