ABSTRACT
In previous chapters using the right techniques, a lower order model of a system can be achieved. Designing the compensator for a high order system highlights the problem of approximating it which is examined in the next chapter. Before that, this chapter introduces a technique for synthesizing a linear quadratic regulator (LQR) which is able to determine the closed-loop eigenvalues on the basis of an optimized criteria. This design technique is the optimal control.
