摘　　要：介绍综合离心外压加载试验系统的组成,根据外压加载系统的工作原理,推导外压加载系统的数学模型,并采用AMESim软件对系统进行了仿真研究,经试验验证比照,证明所建立模型的正确性。针对外压加载系统的非线性和时变性,设计智能PID控制器并通过AMESim和MATLAB软件联合仿真,验证该控制算法的优越性,可提高加载快速性和精度。Thework principle and the composing of Combined Environmental Test System is briefly introduced, and the math model is derived. Simulation study is carry out by using AMESim, and the model is proved to be correct by comparing the result withthe test. Focus on the characteristic of hysteresis, a fuzzy-PID controller is designed and proved that the controller can improve the rapidity and precision by the combined simulation using AMESim and MATlab simultaneously.
