PC-based Data Acquisition
System Overview
In the last few years, industrial PC I/O interface products have
become increasingly reliable, accurate and affordable. Because
of this, PC-based data acquisition and control systems are
widely used in industrial and laboratory applications like
monitoring, control, data acquisition and automated testing.

timesProcess Control Using Takagi-Sugeno Fuzzy Modeling
A fuzzy controller or model uses fuzzy rules, which are linguistic if-then statements involving
fuzzy sets, fuzzy logic, and fuzzy inference. Fuzzy rules play a key role in representing
expert control/modeling knowledge and experience and in linking the input variables of
fuzzy controllers/models to output variable (or variables). Two major types of fuzzy rules
exist, namely, Mamdani fuzzy rules and Takagi-Sugeno (TS, for short) fuzzy rules.

timesProcess Modeling Identification and Control
Models and dynamic characteristics of continuous
processes, Jan Mikles Miroslav Fikar, This chapter serves as an introduction to process control. The aim is to show the necessity of
process control and to emphasize its importance in industries and in design of modern technologies.
Basic terms and problems of process control and modelling are explained on a simple example of
heat exchanger control. Finally, a short history of development in process control is given.

CONTROL THEORY
The better a process’ behavior and inputs are understood and measured, the more its
results can be controlled. However, a process’ performance can be improved even if
its behavior is only approximately known (i.e., a mathematical model of it has been
created). Process models typically are used to develop a PCS, and the task of deter-mining which model and parameters to use is called process identification.
