Robust Control and H-Infinity-Optimization free essay sample

In Section 6 the resulting mixed sensitivity problem is discussed in some detail. It is shown that it can be used not only for robustness optimization or robustness improvement, but also for design for performance. The design method based on the mixed sensitivity criterion features frequency response shaping, type k control and specified high-frequency roll-off, and direct control over the closed-loop bandwidth and time response by means of dominant pole placement. To illustrate these features two design examples are included. In Section 7 a textbook example is discussed hat is simple enough to be completely transparent. In Section 8 the application of the mixed sensitivity method to a benchmark example involving ship course control is described. Sections 9-11 briefly review the theory needed to solve ~-optimal regulation problems. In Section 9 it is shown that the mixed sensitivity problem is a special case of the so-called standard ~Â ®-optimal regulation problem. In Section 10 the frequency domain solution of the standard problem is outlined, while Section 11 describes the main features of the state space solution.
