A study on a variable adaptive law
- 249 Downloads
This paper presents a variable adaptive law, which is robust to bounded disturbances. Combining with the dead zone, the proposing adaptive law uses a sort of the σ-modified adaptive law in the small estimation error region. Viability of the adaptive law, in comparing with the dead zone type adaptive law, is shown by theoretical analysis and a simple numerical simulation.
