A novel adaptive sliding mode control algorithm is derived to deal with seam tracking control problem of welding robotic manipulator, during the process of large-scale structure component welding. The proposed algorithm does not require the precise dynamic model, and is more practical. Its robustness is verified by the Lyapunov stability theory. The analytical results show that the proposed algorithm enables better high-precision tracking performance with chattering-free than traditional sliding mode control algorithm under various disturbances.

研究地基土上水工建筑物滑动设计和计算中存在的问题。利用基坑内压板抗滑动试验成果,确定地基土包括回弹影响后的抗滑动承载能力。采用地基土承受偏心荷载的最大压应力σmax控制地基土与压板的位移和抗滑动形式,可以发生不同的3种最大位移面,形成6种抗滑动形式。根据地基土承受的最大压应力,提出设计抗滑动的计算方法:定量确定地基土与压板抗滑动的摩擦系数计算值,地基土的抗滑动安全系数由指标安全系数控制,修正在地基土上建筑物整体滑动的计算公式,计算预测可能发生的多种最大位移面和抗滑动形式及绘制地基土滑动区轮廓,限定地基土发生平面抗滑动形式时承受的最大压应力值。按拟定方法,回顾分析3座已建水工建筑物,分析计算成果符合实物工况。

Through a pin-on-disc type wear setup, the dry sliding wear behavior of SiC-reinforced aluminum composites produced using the molten metal mixing method was investigated in this paper. Dry sliding wear tests were carried on SiC-reinforced metal matrix composites (MMCs) and its matrix alloy sliding against a steel counter face. Different contact stresses, reinforcement percentages, sliding distances, and sliding velocities were selected as the control variables, and the responses were selected as the wear volume loss (WVL) and coefficient of friction (COF) to evaluate the dry sliding performance. An L25 orthogonal array was employed for the experimental design. Initially, the optimization of the dry sliding performance of the SiC-reinforced MMCs was performed using grey relational analysis (GRA). Based on the GRA, the optimum level parameters for overall grey relational grade in terms of WVL and COF were identified. Analysis of variance was performed to determine the effect of individual factors on the overall grey relational grade. The results indicated that the sliding velocity was the most effective factor among the control parameters on dry sliding wear, followed by the reinforcement percentage, sliding distance, and contact stress. Finally, the wear surface morphology and wear mechanism of the composites were investigated through scanning electron microscopy.

根据滑模控制概念, 提出一种新的可拓控制器。在控制策略设计上分为两个部分,第一个部分是根据系统已知部分设计滑模控制的等效控制, 另一部分为鲁棒控制以解决系统的不确定性因素及外部干扰问题。首先,构造一基本可拓控制器,用所定可拓集的关联函数作为系统状态信息的评价指针, 并在其中植入一组待调增益参数,经参数修正来综合滑模可拓控制的鲁棒控制(滑模的撞击控制),以保证系统的稳定性。最后以一个非线性控制系统的仿真为例来说明所设计的可拓控制器的控制性能。
