中文摘要
      本文探讨了“串级降阶模型误差”（包括控制回路中的惯性环节）对线性二次型（LQ）最优控制的稳定鲁棒性的影响。指出这种模型误差是造成LQ最优控制稳定鲁棒性差的一类重要因素。然后结合输电系统的实际情况分析计算了降阶模型误差对最优励磁控制的微动态稳定鲁棒性的影响。结果表明，被略去的小惯性时间常数对最优励磁控制的微动态稳定鲁棒性有较大影响。
英文摘要
      In this paper the effect of“serial reduced order modelling error”(including the inertia links in regulation loop) on the robust stability of LQ optimal regulators. The effect of the modelling error on the micro-dynamic robust stability of an optimal excitation regulator is calculated according to the actual conditions in a transmission system. The results show that the small inertia time constants neglected have a greater effect on the micro-dynamic robust stability of the optimal excitation regulator.
