摘要现代科技迅速的发展，尤其在军事、基础设施、航海等领域的发展更为迅猛。在军事中的雷达定位，火炮发射、在基础设施建设中的平衡作业、以及在航海中的保持某一平面的水平状态都需要用到平台调平的技术。49105

 本文通过对实现调平平台又稳又快的原则的把握，对调平的系统进行了研究和设计。在阅读研究国内外的有关调平系统资料后，分析了调平系统中的关键技术，并对系统进行了总体上的设计。同时为了研究的方便，在本文中把调平的系统分为三块：1.执行系统2.检测系统3.控制系统。

1）在执行系统中首先根据设计的要求参数选定用液压元件执行。同时也对控制液压系统的关键阀件进行了分析选择。在最后对液压系统进行了设计。

2）检测系统中明确了角度检测的检测方式。通过对系统尺寸的参数，计算出了传感器应有的检测精度。系统中的限位检测是为了确定伸腿的高度。在本设计中的虚腿问题是通过设置压力传感器来检测。

3）控制系统中主要是对调平的策略进行了分析。并对液压缸的实现状态用常规PID的控制方式用MATLAB中的simulink模块进行了仿真。经过仿真此液压缸符合系统的设计要求。

  随后本文便按照各个系统参数要求进行了液压系统的设计、检测系统的选型以及控制系统的设计，经过仿真校核检验符合设计的要求。

Abstract  Modern science and technology developed rapidly, especially in the military, infrastructure, marine and other areas of more rapid development. Military radar,positioning, gun firing, the balance of jobs in the construction of infrastructure, andmaintain a flat horizontal platform leveling technology needed in the navigation.

    In this paper, the grasp of the principle of leveling platform is stable and fast, andreversed the level of system research and design. Reading research on the leveling system information at home and abroad, analysis of the key technologies in the leveling system, and overall design. At the same time in order to facilitate the study, in this paper the leveling system is pided into three: 1. Execution system. Detection system. Control system.

1) The first in the execution system is selected according to design requirement sparameters of the hydraulic system as the execution system. Valves control the hydraulic system analysis options. In the final design of the hydraulic system.

2) detection system clear detection of the angle detection. Calculated parameters of the system size, the detection accuracy in the sensor. The limit detection system is todetermine the height of the legs. In this design, the main problem of virtual leg problem is that by setting the pressure sensor to decision solution.

3) control system the main strategies to determine the swap level. And the hydraulic cylinder to achieve status with conventional PID control module in MATLAB Simulink simulation. After the simulation of this hydraulic cylinder system design requirements.

     Then this article will be in accordance with each system parameter requirements of the hydraulic system design, selection of the detection system and control system design to meet the design requirements, after checking test.
