摘　　要：传统的车齿加工内齿轮具有加工效率高、精度高和成本低等优点,但仍然存在误差。针对车齿加工过程中伺服系统稳态误差大、速度慢以及超调量大等问题,采用前馈和微分负反馈相结合的控制方法,以降低稳态误差,从而改善伺服系统的跟踪性能。通过在MATLAB/Simulink中进行仿真,分析车齿加工内齿轮时的运动轨迹,并对其参数进行分析。最终,通过实验验证了所提方法的有效性。结果表明:引入前馈-微分复合控制策略后,伺服系统的跟随误差和车齿的内齿轮误差明显减小,加工精度明显提高,显著提高了伺服系统的动态性能。The traditional turning tooth processing internal gear has the advantages of high processing efficiency,high precision and low cost,but there are still errors.Aiming at the problems of large steady-state error,slow speed and large overshoot of the servo system during gear machining,the control method combining feedforward and differential negative feedback was adopted to reduce the steady-state error and improve the tracking performance of the servo system.Through the simulation in MATLAB/Simulink,the motion trajectory and parameters of the internal gear machining were analyzed.Finally,the effectiveness of the proposed method was verified by experiments.The results show that the following error of the servo system and the internal gear error of the gear tooth are obviously reduced,the machining accuracy is obviously improved,and the dynamic performance of the servo system is significantly improved by the introduction of the feedforward differential compound control strategy.
