Numerical Control System

Numerical Control System


an automated control system in which signal quantization is effected for both level and duration. Continuous signals arriving at the analogue section of the system (to which are usually connected the controlled object, actuating mechanisms, and measuring transducers) are converted into digital form by analogue-digital converters and are then fed to a digital computer for processing. The processing output is reconverted into continuous signals, which are fed to the actuating mechanisms of the controlled object. Numerical control systems make it possible to improve the quality of control exercised and to optimize the control of complex industrial processes and facilities. Automated control systems for production processes use numerical control.
