摘要: 描述了系统性能极限理论的研究对象、背景和意义, 并简要介绍了系统性能极限理论所涉及到的四个相关问题, 如: 左可逆与右可逆系统、零点与零点方向、极点与极点方向以及灵敏度函数与互补灵敏度函数. 同时, 从H2型性能极限、频域及H∞型性能极限、时域及其他性能极限三方面综述了系统性能极限理论的研究现状, 并对其未来的发展进行了展望.Abstract: This paper gives the description of the research object, background and significance of the system performance limitation theory, and briefly introduces several related issues of the system performance limitation theory, such as the left-invertible and right-invertible systems, the definitions and directions of the zeros and poles, as well as the sensitivity and complementary sensitivity functions. Meanwhile, the research of the system performance limitation theory is discussed from the aspects of the H2 performance limitation, frequency-domain and H∞ performance limitations, as well as the time-domain and other performance limitations in the paper. In addition, the future development of the system performance limitation theory is also explored.
