摘　　要：针对当前凹版印刷机多轴控制的控制精度和稳定性偏低的问题,本研究提出一种新的基于双模糊PID算法的凹版印刷机多轴控制方法。针对凹版印刷机多轴控制系统的非线性特点,利用具有参数功能的双模糊PID器对多电机系统进行改进,同时组建控制模型,进而实现高精度的凹版印刷机多轴稳定控制。为验证本研究方法的有效性,以凹版印刷机多轴控制精度、控制响应时间、稳定性以及控制复杂度作为测试指标,设计一次仿真实验。实验测试结果表明,本研究方法能够有效提升控制精度和系统稳定性,且响应时间和控制复杂度均较低,具有更优的应用性能。Aimed at the low control accuracy and stability of multi-axis control method for gravure press, a new multiaxis control method for gravure press based on double fuzzy PID algorithm was proposed. Aiming at the nonlinear characteristics of the multi-axis control system of gravure press, the multi-motor system was improved by using the double fuzzy PID controller with parameter function, and the control model was built, so as to realize the multi-axis stable control of gravure press with high precision. In order to verify the effectiveness of this research method, a simulation experiment was designed with the multi-axis control accuracy, control response time, stability and control complexity of gravure press as the test indexes. The experimental results showed that the proposed method can effectively improve the control accuracy and system stability, the response time and control complexity become low.The proposed method has better application performance.
