Generally, “solving” the controller design problem means finding the proper mathematical representation of a control action
that meets a set of desired performance criteria. In reality, this is only one part of the solution (albeit an important part);
the control-systems development process also includes steps for selecting the correct hardware – loaded with the proper software
– for the controller module, which is the real end-product of this process (Figure 2.1
The control-system development process begins by first developing the high-level system requirements, which are generally verbal and abstract and rarely point to a recognizable control design problem such as those that ...
