本文用频域法研究了自动焊接装置的最佳控制问题。从理论上导出了具有积分作用的最佳控制器的传递函数,并在实践上予以实现。文中将 Grimble 提供的设计方法,由普通幅相特性方法推广到扩充幅相特性方法,这样设计出来的最佳控制系统不仅能使二次型性能指标为最小,而且使系统具有给定的稳定度或衰减度,改善了调节过程的品质。本文采用的设计方法,无论对低阶系统或高阶系统都同样适用。 In this paper, the frequency domain method to study the best automatic welding equipment control problems. The transfer function of optimal controller with integral function is derived theoretically and implemented in practice. In this paper, the design method provided by Grimble is generalized to the method of expanding the amplitude and phase characteristics by the method of ordinary amplitude and phase. The optimal control system designed in this way can not only minimize the quadratic performance index but also make the system have a given stability Or attenuation, improving the quality of the conditioning process. The design methodology used in this article applies equally to both lower-level and higher-level systems.
