初始设计

Then, in terms of the proposed tuning scheme and frequency-domain control theory, some decupling control methods are studied for the multivariable processes with time delays. The main contribution lies in: 1 For single-parameter diagonal controllers and full matrix controllers of the multivariable control system, a robust tuning scheme is proposed.

首先，给出了系统面临乘性输入、乘性输出，以及加性不确定性时，保证系统鲁棒稳定性的充分条件，并依据此条件，提出了计算控制参数整定范围的解析方法；然后，给出了参数估计方法，用来在参数整定范围内预测初始控制参数；最后，通过主导极点或幅值率调节方法，进一步优化出满足时域设计指标的控制参数值。

Based on this, the author suggests that at the beginning to start diagnostic foundation up, we divide the training period, choose the training method, make sure load tendency and pay attention to the design of the athlete individual training project.

研究指出竞技跆拳道项目体能训练存在的问题；从实战的角度结合项目制胜规律，围绕比赛主要得分手段、能量代谢和腿法、步法以及拳法的技术特点提出体能训练的基本思路；建议在初始诊断的基础上，划分训练周期、筛选训练方法和确定负荷趋势，注重运动员个体化训练方案的设计。

The research points out the existing problems on the physical training of Taekwondo. Besides, from the point of competition, the author puts forward the basic way of thinking of physical training, surrounded with the methods of winning, energy metabolism and leg method, footwork and boxing method. Based on this, the author suggests that at the beginning to start diagnostic foundation up, we divide the training period, choose the training method, make sure load tendency and pay attention to the design of the athlete individual training project.

Through an analysis on mud-clogging mechanism of suction nozzles on wet type sweeper, a concept is suggested, that water ratio in dust nearing the wall of suction nozzle duct should be decreased so the mud stickiness can be controlled under a critical value and not sticking to the duct wall whereas water ratio in central dust passage of the duct is properly increased to satisfy effective dust absorbing. On the basis of the concept, a water spraying device is designed with improvement for suction nozzles. In the device, the water hole numbers, diameters and distribution along the nozzle circumference as well as initial direction of water spraying are all determined according to concrete suction nozzle structures.

通过对湿扫型道路清扫车的吸嘴易被泥土堵塞的机理分析，提出降低吸嘴流道近壁的尘土的含水率，控制泥块的黏性处于临界黏性以下，使泥块不黏附于流道壁面；而将吸嘴流道中心部位的尘土的含水率适当加大，以满足有效压尘的解决思路，并根据这种思路改进设计了一种吸嘴喷水装置，按不同吸嘴的具体结构确定孔数、孔径、孔沿圆周的分布规律和喷水的初始方向等要素。
