WebSep 1, 1992 · The new design procedure eliminates overparametrization while retaining all the advantages of the procedure in [2,4]. It employs exactly p estimates for p unknown parameters and significantly reduces the controller's dynamic order. This enhances the stability properties of the adaptive system and improves parameter convergence. WebFeb 27, 2024 · Example 1.2.1. Here are three different parametrizations of the semi-circle x2 + y2 = r2, y ≥ 0. The first uses the polar angle θ as the parameter. We have already seen, in Example 1.0.1, the parametrization. The second uses x as the parameter. Just solving x2 + y2 = r2, y ≥ 0 for y as a function of x, gives y(x) = √r2 − x2 and so ... indiana university basketball rivals
