Applying control theory concepts in software applications
Control theory is a discipline originated in mathematics and engineering science but was adopted also in psychology, social sciences and other research domains. It deals with influencing the behaviour of dynamical systems. In this article it is shown that concepts of control theory can also be applied to software architectures that have a need for controlling dynamical behaviour. Software applications that react to external input in form of GUI requests, batch input or service calls are in deed dynamical systems whose behaviour depends on current event, environment and actual system state.

Writing correct concurrent programs is harder than writing sequential ones. This is because the set of potential risks and failure modes is larger - anything that can go wrong in a sequential program can also go wrong in a concurrent one, and with concurrency comes additional hazards not present in sequential programs such as race conditions, data races, deadlocks, missed signals, and livelock.
