摘　　要：基于制造集成化对航空发动机叶片的抛光要求,针对叶片抛光过程中抛光力的非线性和时变性难以控制等问题,提出一种建立抛光力控制系统数学模型并进行模糊比例-积分-微分控制的方法。研制了砂带抛光施力和运动机构,以气缸和比例阀为主要研究对象,建立抛光力控制系统的数学模型,结合模糊比例-积分-微分控制原理,设计了自适应模糊比例-积分-微分控制器。对抛光力控制系统进行系统仿真与实验验证,结果表明,所采用的模糊比例-积分-微分控制系统具有快速响应性和较强的鲁棒性,可以满足叶片抛光过程中抛光力的控制要求。Based on the polishing requirements of integrated manufacturing to aero-engine blade, with regard to the non-linear and time-varying change problem of polishing force during thin blade belt polishing process, a method of establishing system mathematical model and using fuzzy Proportion Integration Differentiation （PID） control was presented. Force application and motion mechanism of belt polishing was discussed, and mathematical model of pol- ishing force control system was established by taking cylinder and proportional valve as object. Combining with the fuzzy PID principle, adaptive fuzzy PID controller was designed. The polishing force control system was simulated and experimental verified, and the results showed that the selected control technology had quick response and good robustness. It could satisfy the requirements of polishing force control of blade in belt polishing .
