| Prev: PID Control | Chapter 12 - Frequency Domain Design | Next: Robust Performance |
In this chapter we continue to explore the use of frequency domain techniques with a focus on the design of feedback systems. We begin with a more thorough description of the performance specifications for control systems and then introduce the concept of “loop shaping” as a mechanism for designing controllers in the fre- quency domain. Additional techniques discussed in this chapter include feedforward compensation, the root locus method, and nested controller design.
