摘　　要：给出３组新的ＩＴＡＥ最佳传递函数标准型以及它们的频率特性和阶跃响应；讨论了满足ＩＴＡＥ控制律极值解的唯一性和非唯一性的辩证关系；最后讨论了它们在双容纯时滞二次优化控制系统中的应用．结果是性能指标好，算法简便。Aimed at the problem that VCGA with global convergence sometimes slows the convergence rate down, this paper suggests a hybrid approach called HVCSDA which can reinforces the capability of fine tunning of VCGA as it is near the global optimal solution. This paper also generalizes HVCSDA in order to adapt for a class of the modified VCGA. Two simulation examples show that HVCSDA and its generalization can effectively raize the convergence rate of (a class of modified) VCGA. In the second simulation example, the length of routing of 30 cities TSP is 6.882, it is better than one that is 6.99 by TABU.
