In many industries (such as pharmaceuticals, beverage industries, etc.), bottles are required to be filled up with a pre-determined amount of liquid. Implementing systems using relay logic control can cause them to be inflexible. Programmable Logic Controllers - PLCs - are more flexible in automating various processes, since the behavior of the system can be changed without changing the electrical...
The general purpose of an air compressor is to generate air at higher pressure for use in industrial applications. The steps involved in the process of a compression unit are purification, air filtering and storing the purified air. As the entire process handles air pressure at a large level, even any small miscalculation or misjudging of the parameter may cause big damage to the machinery and also...
In this paper, a PLC controlled simulation of a coupled tank system based on an existing dual-tank educational process control plant is developed. A critical analysis of the plant is carried out in order to obtain all the required parameters to setup the simulated model. Unlike the actual plant, the virtual process control model is not limited to two tanks only but may be reconfigured with ease in...
This paper presents automatic generation control and monitoring operation of Micro Hydro power plant (MHPP), based on Impulse Turbine, synchronous motor with permanent magnet and a servo control spear valve. The key objective of this system is to show the benefits of automatic generation control and Human Machine Interface (HMI) for MHPP. Mainly, turbine governing system covers the automatic generation...
Liquid level as an important in the chemical industry and many other industrial production parameters, the measurement and control effect directly affects the quality of the product, so the liquid level control plays an important role in the industrial production. Because the liquid level of liquid level control system has nonlinear, big lag, outlet valve port mathematical model is difficult to accurately...

This paper selects controller based on Siemens S7-200 and control strategy based on PID, It realizes high-precision control and real-time display of double water tank by PLC...
A method is proposed in which the camera captures the logo of the bottles continuously to fill the bottles with different liquids on a single conveyor based on logo of the bottles. We have used cross correlation image classification method to classify the logo image of the bottle. Accordingly, we have filled the liquids in the bottle. In this system, we interface the result of image in MATLAB R2013...
The electro-hydraulic actuation system was designed and realized by INOE 2000 - IHP for Regional Air Services - Tuzla Airport. It is used on the Cabin Emergency and Escape Trainer CEET B732 for the Sea Survival School. The closed loop control system controller, that implements the actuation system functionality, was designed as a software application using dedicated PLC software tools. Common PLCs...
