紧致域 meaning in English

compact region

In the new method the uncertainty of the system to be controlled is normalized firstly , and then the partition of unity that is subordinated to a open covering of state variables compact set is constructed , and the approximation is realized by using its property that can approximate nonlinear continuous function with arbitrary precision , then the decentralized adaptive robust controller of complex systems and adaptive laws of approximate parameter estimation are designed
该方法首先对被控系统中的不确定性进行归一化处理，进而构造出从属于状态变量的紧致域的一组开覆盖的单位分解，利用其具有以任意精度逼近非线性连续函数的性质，实现了对被控系统不确定性的近似逼近，然后设计了复杂系统的分散鲁棒控制器和参数估计的自适应律，并证明了这种控制器使被控系统的状态及参数估计误差一致终极有界。
