many factors affect yield loss in wheat harvesting with a grain combine harvester and there is no mathematical model to describe the behavior of this complex system. thus in this study, a fuzzy logic controller (flc) was designed, implemented and tested for the automatic settings of cylinder speed, concave clearance, fan speed and forward speed of a model 955 john deere combine. first, the mech...

reaction constants and heat release during thermophilic aerobic digestion of typical secondary and mixed sludges were determined. maximum reaction constant, determined by measuring the amounts of biodegradable volatile suspended solids (bvss) removed, occurred in the temperature range of 55-60 ºc. measurement of heat releases were carried out, at the same range, by the aid of a temperature prog...

Preservation of comfort conditions for buildings’ occupants and minimization of energy consumption and cost are the main targets of the energy and indoor environment management systems. This paper aims to achieve those targets by presenting the optimal operation of chilling systems within the building supervisory control systems using fuzzy control instead of a conventional Programmable Logic C...

This paper describes the design and development of harvesting system for the gantry system to harvest eggplants. For this purpose, the harvesting robot was successfully designed and fabricated for the gantry system to harvest eggplants. The operation of the harvester was controlled by Programmable Logic Controller (PLC). Basically, the limit switches, DC motor, and relay are connected to the PL...

Supervisory Control and Data Acquisition (SCADA) system is an industrial control automated system. It is built with multiple Programmable Logic Controllers (PLCs). PLC is a special form of microprocessor-based controller with proprietary operating system. Due to the unique architecture of PLC, traditional digital forensic tools are difficult to be applied. In this paper, we propose a program ca...

In this paper, an optimized fuzzy controller is presented for the control of the environmental parameters at the building zone level. The occupants’ preferences are monitored via a smart card unit. Genetic algorithm optimization techniques are applied to shift properly the membership functions of the fuzzy controller in order to satisfy the occupants’ preferences while minimizing energy consump...

ABSTRACTThe development of automation technology in various production processes the industrial world is experiencing rapid progress, course this will have consequences, that workforce field must meet adequate qualifications so runs optimally. The partners activity are SMKN 1 Bendo Magetan, East Java. problem competence students about Programmable Logic Controller (PLC) less than optimal. This ...

The Supervisory Control Theory is applied to a manufacturing cell commanded by a programmable logic controller (PLC). By means of local modular approach a methodology that exploits modularity of the plant and of the behavioral specifications models optimal supervisors are obtained without state-space explosion. For the purpose of simplifying the ladder diagram implementation in the PLC, reduced...
