摘要
本文从干扰特性的设计要求出发,提出了一种二自由度控制系统的干扰估计型结构,这种结构的干扰特性和设计参数之间,存在很明显的关系,为系统设计提供了简易可行的方法,分析和仿真表明,按这种结构设计的系统,具有很好的干扰特性,同时对控制对象的模型化误差也有良好的鲁棒特性。
Based on design requirements of system disturbance performance, a new disturbance observer structure in two-degree-of-freedom control system is proposed. In the structure, there exist explicit relations between disturbance performance and design parameters, this provides a convenient design method. Theoretical analysis and simulation demonstrate that the resulting system has perfect disturbance performance and robustness in modeling plant uncertainty.
