Ket : Nonlinear analysis can also be conducted in the frequency domain. It is known that the analysis and synthesis of linear systems in the frequency domain have been well established. There are many methods and techniques that have been developed to cope with the analysis and design of linear systems in practice such as Bode diagram, root locus, and Nyquist plot (Ogota 1996). Frequency domain methods can often provide more intuitive insights into system linear dynamics or dynamic characteristics and thus have been extensively accepted in engineering practice. For example, the transfer function of a linear system is always a coordinate-free and equivalent description whatever the system model is transformed by any linear transformations; the instability of a linear system is usually associated with at least one right-half-plane pole of the system transfer function; the peak of system output frequency response often happens around the natural resonance frequency of the system, and so on. Therefore, frequency domain analysis and design of engineering systems are often one of the most favourite methodologies in practices and attract extensive studies both in theory and application.
