Multiple Devices

In this paper, we design a typical automated packaging salt system, including multiple devices to stir, feed, packaging, weighing and other links. This requires the coordination of all sectors to achieve sequential switch, equipment failure alarming and maintenance. Therefore, salt packaging system adopts PLC control. According to different control objectives and requirements, we allocated the address reasonably; selected PLC and the modules. GX Developer software is used to programming and finally the control panel is designed. After commissioning and practical application, the effect is good, efficient, and precise.

Function Calculation

A software quality evaluation method for control system based on the extension engineering analysis method is proposed. The evaluating index system of software quality evaluation for control system was constructed. The matter elements models were constructed, and the goodness of mechanical design scheme was computed by using goodness evaluation method based on correlation function calculation. Then the pros or cons of system to be evaluated were determined by comparing the goodness value of each evaluation grade. Finally, the practical application showed that the evaluation method was scientific, clear, and effective and had good practicality.

Emissions Control

The combustion process in gas-turbine engines produces emissions, especially nitrogen oxides (NOx) and carbon monoxide (CO), which change dramatically with combustor operating conditions. As part of this study, the application of active feedback control technologies to reduce thermal NOx emissions is modeled numerically and demonstrated experimentally. A new optical flame sensor, designed by Ametek Power & Industrial Products, has been successfully implemented as the feedback element in a proof-of-concept control system used to minimize NOx emissions. The sensor consists of a robust mechanical package, as well as electronics suitable for severe gas-turbine environments. Results from system rig tests correlate closely to theoretical predictions, as described in literature and produced by a control system simulation model. The control system simulation model predicts the efficacy of controlling engine operating characteristics based on chemical luminescence of the OH radical. The model consists of a fuel pump and metering device, a fuel-air mixing scheme, a combustion model, the new ultraviolet (UV) feedback flame sensor, and a simple gain block. The input reference to the proportional emissions control is the fuel-to-air equivalence ratio, which is empirically correlated to the desired low level of NOx emissions while satisfying other operating conditions, such as CO emissions and power. Results from the closed-loop emissions control simulation and rig tests were analyzed to determine the capability of the UV flame sensor to measure and control the combustion process in a gas-turbine engine. The response characteristics, overshoot percentage, rise time, settling time, accuracy, resolution, and repeatability are addressed.

Theoretical Considerations

This paper is divided into three sections. The first of these deals with the basic principles of Criterion-Based Instruction as a form of Data-Based Instruction. Such things as measurement procedures, instructional aims, using task analysis, and maintaining student records are discussed. Secondly, a project using Criterion-Based Instruction at the Townsville Special School during 1982 is outlined. This project utilised the Brigance Inventory materials, with special emphasis on the Inventory of Basic Skills. Finally the result of an evaluation of the use of the Inventories is presented and discussed. Data for the evaluation was obtained from the classroom teachers at the school.
