Excerpt from Servol: Preliminary Proposal for a Programming Language for Real-Time Servo Control
Parameter variables enable communication with the host computer. Every such variable is either 'read only' or 'write only'. Read only parameter variables, declared with the attribute read, are quantities the host computer transmits to servol. Examples are: the position target for a moving robot arm, position limits, thresholds at which interrupts are to be generated, etc. Write only parameter variables, declared with the attribute write, are quantities which servol updates continuously and makes available to the host computer, which can poll them when required, use them to update graphic displays, etc.
Internal variables are named intermediate quantities local to servol, and are used to facilitate the computation of control write and parameter write outputs from control read and parameter read inputs. Internal variables can be initialized to constant values.

Paperback. Zustand: New. Print on Demand. This book sets out to define a programming language for real-time servo control, referred to as SERVOL. The author, an expert in the field, describes SERVOL's design for writing the innermost, real-time control levels for robotics and other similar situations where sensors need to be read and effectors controlled on a continuous, high-frequency basis. The book includes descriptions of the various classes of variables used by SERVOL, a guide to the interpretation loop and the significance of each step in the loop, and a collection of sample code to demonstrate the functionality of SERVOL. The book also includes a discussion of the system protection and security features built into SERVOL's design, including the use of encrypted passwords and the enforcement of defined controls through the use of the "single assignment rule." This book is a valuable resource for anyone interested in the design of real-time control systems for robotics and other sensor-effector systems. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Bestandsnummer des Verkäufers 9781334016042_0
