چکیده

With the advent of digital computers the engineers felt the need of utilizing computer advantages in the industrial process through the centralized control system. This thought led to the introduction of direct digital control (DDC) phylisophy. In this paper the author has presented a brief review of the structure of DDC as well as its working with illustration. The two types of algorithm used for programming as PID controller are discussed. The author has also pointed out the merits of DDC over analog control.Besides a few practical application has also been described.

Quality comparison of direct digital panoramic radiography and computed radiography panoramic

BACKGROUND AND AIM: Digital panoramic X-ray images can be captured using photostimulable phosphors or solid-state detectors (i.e. charge-coupled devices and Flat-Panels). The first category is defined as computed radiography (CR) or semi-direct radiography. The second technology that uses solid-state detectors is known as direct digital radiography (DDR). Both of these technologies have their o...

On Line Determination of Optimal Hysteresis Band Amplitudes in Direct Torque Control of Induction Motor Drives

In conventional direct torque control (DTC) of induction machines, undesirable flux and torque ripples are produced. These occur since non of the selected inverter's voltage vectors are able to generate the exact voltage required to produce the desired changes in the electromagnetic torque and stator flux linkage in most of the switching instances. In addition, when direct torque control is imp...
