Embedded control systems
In this chapter, we make a concise overview of embedded control systems and discuss some aspects of the corresponding hardware and software which is used in these systems. The embedded control systems are digital systems and their performance is affected by sampling and quantization errors. That is why, we present some basic elements of fixed-point and floating-point computations and describe the rounding errors associated with these computations. In case of fixed-point arithmetic, the emphasis is put on the scaling problem, which is the most important issue in using such arithmetic. We describe briefly the stages of embedded controller design, controller simulation, and implementation.
