查询词典 air-proof

As one of the common facilities in manufacturing enterprises, air compressors are widely used due to their capacity of producing compressed air. However , an authoritative survey shows that air compressor system consumes about 86%of the total energy cost within five years compared with purchase price that only accounts for 8% of total cost. This high volume of energy consummation invisibly increases enterprises' operational cost. However ,within the 90% of the cost for energy, main tenance and repair , 50% can be saved.

压缩机作为制造厂最常用的设备之一，其所产生的廉价适用的压缩空气能源备受许多企业家青睐，据权威机构调查，空气压缩系统在五年的总成本中，运转能源消耗费用占约86％，压缩系统初期购置费用仅占总成本的约8％，其高额的运转能源费用无形中增加了企业运营成本；然而人们却不知道这里占近90％的能源及保养修理费用却是有50％以上是可能不必支付的。

So in this paper based on the characteristics and the optimum state theory of the vehicle, some kinds of control schemes are compared and discussed, and the fuzzy PID control scheme is adopted at last. The relation between air-cushion pressure and fan rotational speed on the optimum driving state is studied. The cushion pressure is used as controlled variable and the fan revolution is used as regulated variable. And transducer and fan motor are actuators.Based on the structure and operating properties of half-tracked air-cushion vehicle, the control system scheme and structure are presented. A control scheme using the self-tuning PID fuzzy logical controller is adopted. Fuzzy rules are set up and some researches have been done for fuzzy tuning method. At the same time the real-time measurement scheme by computer control is proposed, and electric circuits are designed. In the control system of half-tracked air-cushion vehicle cushion pressure P〓 is used as controlled variable and the fan speed n〓 as regulated variable.

因此本文以半履带式气垫车的特性和最佳工作状态理论为指导，通过对各种控制方法的比较与探讨，提出采用模糊PID控制方案，并且研究了在最佳工作状态下垫压及风机转速的关系，提出气垫压力作为控制参数，变频器和风机电机为执行机构，风机转速为调节量；主要进行了自整定模糊PID控制器的设计，研究了自整定PID模糊控制器的实现方法，编制了模糊控制规则，制定了模糊控制参数查询表，并分析了影响自整定模糊控制器相关的影响因素，确定了模糊控制表；为了实现半履带式气垫车的自动控制，还提出了计算机模糊控制系统的原理与结构，设计了相应的测量电路与控制软件。
