In this article, utilizing Delphi 7.0 as the development platform, we design the system to collect or record measurement data through electronic digital caliper and digital table, compute control parameters of quality control chart, draw the process control chart of controlled objectives and read, analyze and manage the measurement data.

In this article, we study digital repetitive control to track continuous-time periodic references. Sampled-data control gives a very natural platform for studying digital repetitive control, and in particular, sampled-data H∞ filtering is particularly suitable for this. The link is provided by introducing internal model control. This leads to a close connection between robust repetitive control...

This application report presents a TMS320F280x based digital control design and implementation of a high frequency dc-dc switching power supply. Starting with a dc-dc buck converter and a given set of performance specifications, different control blocks and parameters, used as in the analog control design approach, are reviewed prior to the control design in digital domain. The control loop is ...

— In this paper, we describe a new methodology applied to solving in-class problems. The aim is to increase the student's participation and motivation, and, consequently, the acquisition of knowledge and skill in digital systems. We present the use of an interactive docent tool, Educlick, which has been adapted to these problems' classes. Educlick is based on the use of electronic answer remote...

We present and evaluate a class of medium access control protocols for wireless digital networks. The presented protocols are stable, they induce good delay characteristics and they possess resistance to feed back errors. We also evaluate a system deploying the IEEE 802.11 protocol, instead. In the presence of relatively tight admission delay constraints, the latter is significantly inferior to...

Thanks to the digital revolution, digital signal processing and control has been widely used in many areas of science and engineering today. It provides practical and powerful tools to model, simulate, analyze, design, measure, and control complex and dynamic systems such as robots and aircrafts. Gene networks are also complex dynamic systems which can be studied via digital signal processing a...

A digital signal processor (DSP) solution is proposed to control an H-bridge DC-DC isolated output power converter. The multiple mode digital controller is evaluated with an existing Westinghouse 1-kW power stage. The digital controller was developed using the dSPACE [1] rapid prototype development system and MATLAB/Simulink. It is evaluated using a real-time digital control development platfor...

Contract and rights management – and thus property rights protection – has gained increasing importance as a quality standard in brokerage and electronic commerce environments. Contract and rights management provides information on the legal relationships associated with digital assets, as well as intellectual property rights protection and the enforcement of rights. However, many brokerage and...

The so-called digital control power source, also referred to as a "loop inside the processor" refers to the system controller can execute the control algorithm in the digital domain. It is necessary to compare the two to produce strings of digital pulse width to drive the power switch, but instead of using a conventional analog PWM comparator. It will all analog system parameters into a digital...
