为了优化机械连杆的锻压工艺，提升机械连杆锻件的力学性能和耐磨损性能，分别采用常规PID控制和模糊PID控制方法对铝基复合材料机械连杆锻压过程进行控制，并对两种控制方式下锻压机械连杆的室温力学性能和耐磨损性能进行了测试与对比分析。结果表明：与常规PID控制相比，采用模糊PID控制时连杆抗拉强度和屈服强度分别增大了36和45 MPa，经20 min磨损试验后连杆的磨损体积减小42.3%。模糊PID控制方式显著优于常规PID控制，采用模糊PID控制的锻压机械连杆的力学性能和耐磨损性能均优于常规PID控制，有利于提高锻压机械连杆的综合性能。

In order to optimize the forging process of mechanical connecting rod and improve the mechanical properties and wear resistance of mechanical connecting rod forgings, the forging process of mechanical connecting rod with aluminum matrix composites was controlled by conventional PID control and fuzzy PID control, and their mechanical properties at room temperature and wear resistance under the two methods were tested and analyzed. The results show that compared with the conventional PID control, the tensile strength and yield strength of the connecting rod produced by the fuzzy PID control increase by 36 MPa and 45 MPa respectively, and the wear volume after wear test for 20 minutes decreases by 42.3%. Furthermore, the fuzzy PID control method is significantly better than conventional PID control. Thus, the mechanical properties and wear resistance of the forged mechanical connecting rod produced by fuzzy PID control are better than that by conventional PID control, which is beneficial to the improvement of comprehensive performance of forged mechanical connecting rod.
