Abstract
An important branch of control theory is concerned with the frequency response of a system. This approach to the investigation of system performance provides an alternative to the transient-response and root-locus methods and is favoured by many control engineers, especially those with an electrical-engineering background. The frequency-response method considers system behaviour due to sinusoidal forcing; the information obtained can be used to determine closed-loop stability from the open-loop frequency response in a manner analogous to the root-locus method.
