Automation means Delegation of human control to machine. A PLC (Programmable Logic Controller) is a device that was invented to replace the necessary sequential relay circuits for machine control. A SCADA (Supervisory Control & Data Acquisition System) is used to control the process where person cannot go or stay for longer period. The aim of tis paper is to provide information about hoelectric...

Programmable Logic Controller (PLC) has been widely used in the industrial control. Inherently, the PLCbased system is a class of Hybrid Dynamical System (HDS) in which continuous state of the plant is controlled by the discrete logic-based controller. This paper firstly presents the formal algebraic model of the PLC-based control systems which enable the designer to formulate the various kinds...

This paper emphasize on controlling the process variable parameters such as level and flow with real time implementation of gate control of hydroelectric power plant using Programmable Logic Controller. In this work, a programmable logic controller is used as an industrial computer playing the role of a control device and push buttons, level and flow sensors provide incoming signals to the cont...

Programmable logic controller (PLC) can be programmed for various purposes, one of which is to design a fire extinguishing system, by assembling several components PLC, solenoid, springkle, powersupply ,adapter ,smokedetector, heatdetector, pilotlamp, pushbutton, relay, selector switch. the program settings detect smoke and high temperatures that occur in event fire. if sensor detects temperatu...

the depth control systems used in iranian tractors are mechanical and they produce variable tillage depth in uneven field surface. in this research a rotary type electronic control valve was designed and constructed. by using this valve, electro-hydraulic tillage depth control system was developed and installed on the tractor. the control system was composed of: a depth sensor, a programmable l...

This paper presents a design and implementation of a monitoring and control system for the three-phase induction motor based on programmable logic controller (PLC) technology. Also, the implementation of the hardware and software for speed control and protection with the results obtained from tests on induction motor performance is provided. The PLC correlates the operational parameters to the ...

In this paper an innovative method for robotic manipulator kinematic control and supervision is proposed, both locally, by operator panel, both remote by the use of short-message. A programmable logical controller (PLC) is adopted to obtain a versatile and applicable solution in any robotic system. In particular the problem of end effector positioning in a desired point of the work space of an ...

A common practice is to design a controller by plant observations (i.e., experiments) and to optimize some of its parameters by trial-and-error. This paper proposes a genetic algorithm for the automation of the search procedure. A chemical process is introduced to explain the proposed approach. The process is controlled by a programmable logic controller (PLC). A genetic algorithm was implement...
