A compiled-type numerical control system based on asynchronous operating mode was proposed. The system constitutes of data center, motion control cards and communication system, solving the contradiction between real-time and openness property. The architecture and work procedure of the system were illustrated. According to the features of system that are large amount of data transmission, high transmission speed requirements and numerous connected devices, data compression technology of NC system was studied. LZW compression algorithm was chosen after contrast, and compression based on PC software was implemented in data center while decompression based on FPGA hardware being implemented in motion control cards. The simulation and experiment results show that data compression ratio could be under 10%, compression and decompression speed are fast and system requirements are satisfied.

In the industrial workplace, automation enhances productivity and quality while reducing errors and waste, boosting safety, and providing greater flexibility to the manufacturing process. Industrial automation, in the end, results in enhanced safety, dependability, and profitability. Increased productivity is achieved by automating the welding machine for conveyer rollers. Many departments are included in this project like design, fabrication, testing, etc. The movement of welding torch with respect to workpiece can be automated with the help of pneumatics along with use PLC control system. Accuracy is the key factor on which the rate of success of the project can be measured. Hence, tried to standardized the project as much as possible by using standard data and equipment. Automation systems are increasingly displacing humans in the workplace. One of the advantages is that the human workforce will have more time to focus on more innovative projects as a result of the transition. All the required parameters are to be considered while designing the machine components. According to design, fabrication is done with the guidance of experts from the company as well as project guide.

This paper was presented at a joint meeting of the Institute with the Institution of Electronic and Radio Engineers in London on 15 January 1975. The theme of the meeting at which six papers were discussed (a selection of which will be published in the Journal) was Advances in Airborne Equipment for Navigation and Freight Control.Modern data processors because of their increasing power and flexibility are increasingly used for a variety of functions in modern aircraft, both civil and military. It might seem that a flight control system could be designed of the form shown in Fig. 1, with a powerful central processor taking in signals from all the relevant sensors, gyros, pressure sensors, radar, &c., and operating the control surfaces so as to drive the aircraft along any desired course. But such a system would be quite inadequate in two vitally important aspects: there is no facility for inputs from the aircrew and no account has been taken of failure cases. These and other factors drive the control system designer inexorably towards a total system structure very similar to the type currently used in operational aircraft. There are of course a wide variety of such systems, but most of them are characterized by a number of common features.

A synchronous detection NC system is introduced based on an open multiracial PMAC controller and Panasonic servo motor where IPC is used as host computer, PMAC as control system center, and Panasonic servo AC system is used as drive. The PID control model of the servo motor is built with Simulink. When Kp equals to 0.55, KI equals to 1. 8, and KD equals to 0. 04, the simulation is carried out and the result meets the requirement of 0. 05 second. By using Honey Bee NC cutting machine to complete synchronous detection and control of the two servo motors, the synchronous operation error is obtained. The result shows that the servo motor synchronous control system, whose absolute average of relation deviation is 2.919%, reaches the requirements of technology and precision of gas cutting NC system.

This study implements the auto start control system on an electric motor 3 phase C4Feeding pump when the discharge pressure is low-low (4.3 kg /cm²). The C4 feeding pumpmotor was initially manually operated from the local control station, this was very ineffectiveand inefficient because it still relied on the field operator to operate the pump motor and whenthe plant was in normal operating it is very risk if the field operator late to operate motor then itwill impact to quality of the product, and if the delay time to operate motor is too long then planthave to shut down, therefore improvement is needed in the C4 feeding pump motor controlsystem. In this paper, various types of 3-phase motor control are explained which allow it to beapplied to the C4 feeding pump motor that are on-off, inverter, and variable speed drive andefficient selection of the three systems control of the motor. Software and hardware used in thisthesis work are DCS CENTUM VP Yokogawa.
