High-speed current controller for vector controlled permanent magnet synchronous motor (PMSM) is presented. The controller is developed based on modular design for faster calculation and uses fixed-point proportional-integral (PI) method for improved accuracy. Current dq controller is usually implemented in digital signal processor (DSP) based computer. However, DSP based solutions are reaching...

In this work, we present an industrial cold walled Atomic Layer Deposition (ALD) system, which can be controlled by either a traditional programmable logic controller (PLC) system or field-programmable gate array (FPGA) prototyping board. This work presents FPGA that takes ladder diagram (LD) control for PLC and converts to Verilog HDL programs such the board is used real application. We explor...

......The off-chip memory subsystem is a significant performance, power, and quality-of-service (QoS) bottleneck in modern computers, necessitating a high-performance memory controller that can overcome DRAM (dynamic randomaccess memory) timing and resource constraints by orchestrating data movement between the processor and main memory. Contemporary DDRx (double data rate memory interface tech...

This paper is a design and implementation of a monitoring and control system for industrial mixer using PLC .This mixer used for an effective, reliable and highly flexible method for the control of processes within an Industrial environment. The objective of this study is to simulate the control an industrial mixer and by doing this we can develop a program that can be used for the actual imple...

The paper presents a methodology of designing control logic that is implemented by industrial programmable logic controllers. The approach is based on discrete-event model of a plant to be controlled and a set of interlock and sequential specification models. Supervisory control theory is used to test the controllability of the specifications and in the final stage, to derive a model of the adm...

An overview on the different steps involved in the development of a logic control algorithm from the informal specification to the final implementation on a programmable logic controller (PLC) is given. Based on this overview the steps in the development process are presented in detail. An example is used throughout the paper to illustrate the methods. The approach uses Signal Interpreted Petri...

In this paper, we propose a dynamic approach to programmable logic controller (PLC) reconfiguration that is based on the IEC 61499 standard for distributed, real-time control systems. With this form of reconfiguration control, contingencies are made for all possible changes that may occur. We illustrate this approach with a simple system configuration that uses Rockwell Automation's Function Bl...

This paper describes an emerging theory on the role that representations play in engineering problem solving. Modern cognitive psychology has shown that not only do problem solvers use different representations to store information and ideas, the representation itself influences the problem-solvers’ solution approach. I extend this notion to the engineering domain, and illustrate it with an exa...

Microprocessor Measuring Station (MMS) is a type of programmable logic controller fully developed and designed in Mining and metallurgy institute Bor, Serbia, for monitoring and process control, mainly in copper production plants. It is based on MC68HC11 microcontroller. The paper presents a structure of executive and control program with respect to synchronization of two most important events:...
