| description | Background. The paper considers the use of positional control in medical
technology. It is shown that positional control methods are used in control systems of dryair
sterilizers, for processing medical instruments, in incubators for premature newborns, in
systems for maintaining a given oxygen concentration in extracorporeal membrane oxygenation
devices, in biochemical analyzers, in anesthesia and respiratory apparatus. Materials
and methods. The paper presents a comparative analysis of various on-off control systems.
On the basis of simulation studies, effective options for improved systems have been identified.
Despite its undeniable advantages (low cost, ease of use, simplicity of hardware implementation),
on-off control has a huge drawback – a significant amplitude of fluctuations
of the controlled quantity relative to the task. To eliminate this disadvantage, improved
methods of two-position regulation were proposed (two-position regulation with additional
impact on the first derivative, two-position static regulation and improved two-position static
regulation). Results. As a result of simulation modeling, it was proved that the use of advanced
methods of on-off control improves the quality of control with ease of implementation.
The analysis of the results of simulation modeling of various control methods showed
that the improved on-off-static control has significant advantages – a minimum deviation
from the set value, as well as the absence of a static error. At the same time, there is a disadvantage
in the form of an increase in the number of relay activations, which reduces its
reliability. Conclusions. The conducted studies allow us to formulate recommendations for
the creation of positional control systems in medical technology. |
