Abstract
A comparison is made between two types of adaptive control algorithm. The first type is based on Lyapunov functions, and mechanical energy considerations play a key role in their construction. A second method studied involves a majorizing function approach in which a linear function bounds the modeling error which implicitly involves different types of nonlinearity. A gravity vector nonlinearity is studied as an example. This latter method is more of a dominant eigenvalue method and is compared to the time constant approach using the Lyapunov functions.<>
