本文考虑一个能反映系统参数、结构变化的增广二次型性能指标,在此指标下求出“鲁棒性”输出反馈控制器应满足的一组必要条件,给出设计“鲁棒性”控制器的步骤并建立相应的计算机辅助设计(CSCAD)程序。算例表明,用本文提供的程序设计的系统,性能有明显改善。
In this paper, an augmented quadratic performance index that can reflect the system parameters and structural changes is considered. A set of necessary conditions for the “robust” output feedback controller to be obtained under this index is given. The “robustness” Controller steps and the establishment of the corresponding computer-aided design (CSCAD) program. The examples show that the performance of the system designed with the program provided in this article has been significantly improved.
