查询词典 parameter estimation

In our design, the main assumption is that the regressor vector satisfies certain Lipschitz condition; the key procedure is that we transform the error system to the traditional form with the parameter estimation error multiplying the"regressor vector"; and the"regressor vector-based"update law comes from the combination of the gradient algorithm with a σ-modified term.
