摘　　要：针对8 MN液压机的电液比例控制系统,建立了比例压力控制系统和比例速度控制系统的数学模型。为提高控制系统的性能,引入模糊自适应PID控制策略。在MATLAB中的Simulink环境下对系统进行仿真分析,分析的结果表明模糊自适应PID控制策略有效地改善了系统的控制性能。研究结果对于液压机液压系统的改进优化具有一定参考价值。The mathematical models of proportional pressure control system and proportional speed control system concerned with 8 MN hydraulic press are established. In order to improve control system＇ s performance, the fuzzy adaptive PID control strategy is introduced. System simulation analysis is carried out in MATLAB Simulink environ- ment. The results show that the fuzzy adaptive PID control strategy is effective to improve the control performance of the system. The research results provide reference value for the improvement and optimization of hydraulic press.
