Abstract
In recent years, approaches to control performance
and resource optimization for embedded control systems have
been receiving increased attention. Most of them focus on theory,
whereas practical aspects are omitted. Theoretical advances
demand flexible real-time kernel support for multitasking and
preemption, thus requiring more sophisticated and expensive software/
hardware solutions. On the other hand, embedded control
systems often have cost constraints related with mass production
and strong industrial competition, thus demanding low-cost solutions.
In this paper, it is shown that these conflicting demands can be
softened and that a compromise solution can be reached. We advocate
that recent research results on optimal resource management
for control tasks can be implemented on simple multitasking
preemptive real-time kernels targeting low-cost microprocessors,
which can be easily built in-house and tailored to actual application
needs. The experimental evaluation shows that significant control
performance improvement can be achieved without increasing
hardware costs.
