摘　　要：将先进的电液比例控制技术与计算机控制技术相结合,对六面顶金刚石压机压力控制系统进行了设计,建立了该压力控制的数学模型。运用常规PID控制器的设计方法,设计出了模糊自适应PID控制器,并在MATLAB环境下进行仿真实验。结果表明,采用该控制算法,系统的调节时间缩短,响应速度加快,适应能力和鲁棒性得到提高,系统具有更好的动态特性和稳定性,有效地减少了压力的波动。In this paper, advanced electro-hydraulic proportional technology and computer control technology are employed to set up the pressure control system and the mathematical model of the hexadron synthetic diamond press. A fuzzy adaptive PID controller is designed through the conventional PID methods. At the same time, the methods of pressure control system is simulated, the results showes that such a fuzzy adaptive PID controller has advantages of shortening the time for system readjustment, quickening the response speed, improving the adaptability and robust of the system, advancing dynamic property ＆ stability. All these can reduce the fluctuation of pressurd effectively.
