Web25 Oct 2016 · The purpose of this paper is the design of fractional-order robust lead–lag controller for systems with unstructured uncertainty. Controller's structure is such that it can be considered as a product of a set of fractional-order lead–lag controllers. The innovation of this research is using a new method and solving an optimisation problem ... WebLag-Lead Compensators. The lag-lead compensator is the analog to the PID controller. The lag-lead compensator can meet multiple design requirements: the lag component reduces high frequency gain, stabilizes the system and meets steady state requirements, while the lead component is used to meet transient response design requirements.

Lead–lag compensators influence disciplines as varied as robotics, satellite control, automobile diagnostics, LCDs and laser frequency stabilisation. They are an important building block in analog control systems, and can also be used in digital control. Given the control plant, desired specifications can be achieved using compensators.
