This chapter explores the modeling concept of digital control systems. The configuration includes a digital-to-analog converter (DAC), an analog subsystem, and an analog-to-digital converter (ADC). The DAC converts numbers calculated by a microprocessor or computer into analog electrical signals ...

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...
This paper presents a new technique of designing a direct digital controller for a single-phase pulse width modulation (PWM) converter system, based on closed-loop identification. It is difficult to analytically design a controller due to the double loop structure of the PWM converter control syste...

Classically, when considering the design of a new frequency synthesizer, two basic approaches have been common: phase-locked loops (PLL) and direct digital synthesis. The choice is not always clear-cut; often the designer must make trade-offs or design additional circuitry to compensate for the ...
Ian Grout, in Digital Systems Design with FPGAs and CPLDs, 2008 10.3 Case Study 1: DC Motor Control 10.3.1 Introduction In this case study, a digital controller is developed to control the speed of a DC electric motor. The overall control system model will be developed in MATLAB® [9...
A technique is presented for the design of a continuous nonlinear multivariable control algorithm from a set of simple, linear control models. The coefficients of the linear control models are dependent on the steady state operating point. The technique makes use of line integration and the method...
Design machines Machine design, machine building, and machine control have historically taken place separately, and correspondingly, machine tools are not well integrated systems addressing an automation or fabrication need. However, digital fabrication tools ... N Peek,J Coleman - Siggraph: Studio 被...
Understanding the influence of the control system on the performance of vibratory gyroscopes is important during the design of such devices. The ability of the control system to reduce the effects of resonator imperfections, on the gyroscope performance, was investigated. The analysis of the control ...
