气动程序气控系统凭借良好的抗强磁性、抗强辐射性等优点,被广泛用于自动化生产线.其可靠性直接影响自动化生产线的经济稳定运行.干扰信号的分析及消除处理是复杂气动程序气控系统设计的关键,也是设计的难点.为了提高复杂气动程序气控系统的运行稳定性,以气动机械手为例,借助其全功能图,分析探讨了干扰信号的消除方法,提出人为制造控制信号与复现信号相"与"来消除复现信号干扰的方法,为复杂气动程序气控系统的设计提供了理论依据.%Pneumatic control system is widely used in automatic production line for its advantages of strong magnetic resistance and radiation resistance. Its reliability directly affects the stable operation of the automated production line and its benefits. Analyzing and eliminating the interference signal is the key point and difficulty in the design of the complex pneumatic control system. In order to improve the operation stability of the complex pneumatic control system, the elimination method of the interference signal is analyzed and discussed in the pneumatic manipulator control system by the full functional diagram. By AND operation between the artificial signal and the recurrent signal, the reappearance signal interference is eliminated. This method provides a theoretical reference for the design of complex pneumatic control system.
