摘　　要：对一类带非线性扇形区域约束的时滞系统的绝对稳定性进行了讨论,得到了一些易于用LMI计算的时滞相关稳定性准则.在推导过程中,避免了引入模型变换和交叉项技术,有效地降低了保守性,实例表明结论要优于已有的一些结果.The problem of absolute stability of time-delay systems with sector-bounded nonlinearity has been addressed. Some delay-dependent stability criteria are obtained and can be easily formulated in the form of linear matrix inequalities（LMIs）. We have avoided using model transformation bounding technique for cross terms through derivation of the stability criteria. Numerical example has shown improvements over some existing result.
