摘　　要：将耗散不确定性引入到不确定广义系统中,在状态空间下,通过线性矩阵不等式(LMI)的方法,研究了一类不确定广义时滞系统的鲁棒耗散控制问题.给出了此类不确定广义系统严格耗散的充分条件,然后设计了此类不确定广义系统的鲁棒耗散控制器,最后通过数值算例验证了定理的可行性.The notion of dissipative uncertainties is proposed for singular systems with uncertainties. In state space, the robust dissipative control problem for a class of singular time-delay systems with uncertainties is discussed by using the linear matrices inequalities（LMI）. The sufficient condition of strict dissipativity for this kind of singular systems is then obtained, the robust dissipative controller for the class of singular systems with uncertainties is also given. Finally, the feasibility of the theorems is testified by the numerical example.
