The objectives of an automatic control system are to regulate the process to meet the final product specifications and minimise waste production and energy consumption, hence lowering the environmental impact of the process and maximising the production rate, while ensuring safe operation. Because operating as close as possible to these maximum or minimum objectives are most profitable.
We all know how a small, trivial thing can escalate and turn into a big problem. A tiny decimal point can make all the difference. Consequently, it’s important to know what can go wrong if even a small variable is set incorrectly, and of course how to detect if there are any potential problems that can develop within our control system.
