Controller implementation using novel processors - Case study III

In this chapter the application of a number of quite different processor architectures to the design of digital controllers has been discussed. The Intel 2920 can be used to implement PID, Smith Predictor and Dahlin type algorithms. The FAD based controller requires rather more external logic than a 2920-based design but it is capable of dealing with plants and controllers of essentially unlimited complexity. The external logic is needed both to provide data conversion facilities and to overcome the problems of slowing the circuit down to sampling speeds appropriate for control systems.
