摘　　要：对振动试验台电液伺服全数字控制系统进行了工程设计,建立了系统的数学模型。根据结构不变性原理,设计补偿装置,减少了伺服系统慢时变或未知非线性参数的影响。本文针对一般模糊控制算法存在的问题,采用控制规则智能调节因子和Fuzzy/PI分段控制等一系列措施,克服了传统模糊控制器的缺陷。仿真结果表明上述控制系统优于传统的线性控制。The electron-hydraulic servo system of vibration was analyzed, and its model of loading mechanism and system was set up. Using the structure invarianee principle in electron-hydraulic servo system, compensation system was designed, which decreases the influences of slow time-varying or unknown nonlinear parameters on servo system. Intelligent regulatory factor and Fuzzy/PI combining control algorithm were adopted in the electron-hydraulic servo system. The result of simulation shows that the proposed control system is more effective than conventional control system.
