Ball type surface controlled safety valve 地面控制的球型安全阀
Robust adaptive dynamic surface control for nonlinear uncertain systems 非线性不确定系统鲁棒自适应动态面控制
The method is called dynamic surface control . traditional backstepping algorithm requires repeated differentiations of the modeled nonlinearities 传统的回馈递推方法要求对模型非线性的多次微分。
The conductivity - temperature property of gas sensor made by nano - sized sno2 powder has typical surface controlled sensor ' s characteristic , the conductivity peak is about 130 用sno _ 2纳米粉体制成旁热式气敏元件,所制元件的电导-温度特性呈现明显的表面控制型特征,其电导峰出现在130左右。
Study proves that the accuracy of the underground control measures is much more important than the accuracy of the surface control network , and the basic principle applies to the vertical breakthrough 通过计算它们的相关误差椭圆确定贯通点的贯通误差结果证明,地下控制网的精度比地面控制网的精度更为重要。
