ABSTRACT
In this chapter we will look at synthesizing a compensator for a high order system. One strategy is to consider a lower order model of the process, Gr(s), and design a lower order compensator Cr(s). In this way, the regulator is bound to work well for the lower order system (see Figure 9.1), but not necessarily for the original model G(s) (see Figure 9.2). Therefore, the efficacy of the project needs to be verified (with numerical simulations).
