The plastic industry is a very important manufacturing sector and injection molding is a widely used forming method in that industry. The contribution of this work is the development of a strategy to retrofit control of an injection molding machine based on an embedded system microprocessors sensor network on a field programmable gate array (FPGA) device. Six types of embedded processors are in...

In order to communicate with a PLC (Programmable Logic Controller) flexibly and freely, a data communication model based on the PLC's free port is designed. In the structure of the model, a distributed data communication environment is constructed by using Ethernet and serial adapters. In the communication algorithm, a method of queuebuffer for multi-threaded is used to improve the real-time of...

A unique family of high-speed, microprogrammable asyn-chronous controller (MAC) modules is described in this correspondence.Each MAC module consists of two fundamental mode machines thatcommunicate by means of a handshake interface that permits it to bedriven by any programmable logic device including ROM’s. Any statemachine controller design@ with a MAC module will operate ...

The rapid advances in very large scale integration (VLSI) technology lead to implement modern high speed digital controllers with excellent performance, compared to traditional analog control systems. The field programmable gate array (FPGA) devices provide programmable system-on-chip (SoC) environments for designing powerful ASIC controllers with dedicated architectures. This paper presents a ...

In this paper a PI based adaptive control system is developed to control an organic Rankine cycle power plant. In particular, the control of the turbine speed during the transient between the normal operation mode of the system (connected to the grid) and the islandmode (connected to a stand-alone load) is of main concern. A control algorithm suitable for the implementation on a programmable lo...

In this paper, the robot with three wheels is implement and its motion is controlled . two of robot’s wheels are activated by DC motors. The main PID controllers are implemented with a Field Programmable Gate Array(FPGA) for independent robot movement . a FPGA controller communicate with a PC with PCI card(PLX9052) so that the movement of wheels can be displayed on the monitor through PCI card ...

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...

A test procedure for testing mainly the boundary scan cells, and testing partially the test access port controller in programmable logic devices, and field programmable gate array devices, is suggested. The test procedure involves; the configuration of programmable logic devices or field programmable gate array device, the application of test vectors, and finally the verification of the respons...

Accurate simulation provides a significant means for cost reduction during planning and operation of manufacturing installations. Within the projects Realistic Robot Simulation the standards Robot Controller Simulation (RCS) Interface and Virtual Robot Controller (VRC) Interface were defined by international consortia of leading car makers, robot and simulator manufacturers and line builders, w...
