查询词典 Hermite polynomial

The problem of stabilizing networked PI control systems with fuzzy logic compensation is studied by applying the extension of the Hermite-Biehler theorem to the quasi-polynomial stability problem.

该方法的优点是可利用现有的确定性系统的设计方法设计控制器，缺点是由于缓冲区将时滞都转化成最大时滞，降低了系统应有

To avoid these shortcomings, this paper uses particle swarm optimization approach, instead of Gauss-Newtonian algorithm, to optimize projecting direction, and applies Hermite polynomial, instead of piecewise linear regression, to fit ridge function.

但一般投影寻踪回归算法构造技术较为复杂，采用多次局部光滑回归，计算量较大，外推较为繁杂，容易陷于局部解。

The relevant interpolation algorithms include Lagrange interpolation formula, Newton polynomial interpolation, Hermite's interpolation, cubic spline; the relevant fitting algorithms include least square method, Chebyshev multinomial fitting algorithms and so on.

Ythagorean hodograph curves enjoy a number of remarkable properties, such as, its offset curves have exact rational representations; the arc length function of a Pythagorean hodograph curve is simply a polynomial function of the curve parameter; and the lower degree Pythagorean hodograph curves have intuitive geometrical interpretation.

H曲线具有诸如有精确的有理 Offset、弧长函数可由多项式函数表示以及几何解释优美等一系列优良性质。基于复分析方法，避免了实分析讨论中出现的复杂表示及繁琐计算，构造了满足给定 C1 Hermite插值条件且以C1拼接连续的三次 PH曲线偶。该曲线偶可灵活处理拐点，从而克服了一般三次 PH曲线因恒凸而无法处理拐点的缺陷。
