Then we study the idempotent-separating congruences on the orthogroups with group kernel normal systems and give it a simple rep. 利用群核正规系讨论了纯正群的幂等元分离同余。
Properties of Switched Normal Systems(NS) with Disturbance NORMAL切换系统在干扰下的性质
But the research of normal systems is ripeness. 而正常系统的研究已趋于成熟。
While it has been extended quadratic stability and stabilization in the normal systems to the interval systems. 并把正常系统中二次稳定,二次可镇定的概念推广到区间系统,提出了区间系统二次稳定、二次可镇定的概念;
Compared with the normal systems, descriptor systems describe some of the actual systems better. 相对于正常状态空间系统,广义系统能够更好地描述一些实际系统。
