【摘要】 本文给出了一种含有多种输出量的多机电力系统输出反馈控制用数学模型,为控制器反馈变量的选取提供了基础。此外,本文还提出了一种求解分散输出反馈增益,亦即求解有控制结构约束的Levine—Athans方程组的新方法——直接送代解法,并证明了该算法的收敛性。计算结果表明,该算法与其它算法相比,在求解精度和计算速度方面具有十分显著的优越性。更多还原

【Abstract】 A mathematical model used in the output feedback control of multimachine power systems is presented in this paper. The model, which includes more output variables than usual, provides a basis for selecting the feedback signals of the controllers. Besides, a new algorithm for finding the decentralized outout feedback gains, i.e., solving the Levine-Athans equations with control structure constraints is proposed. Computation results show that the algorithm is greatly superior to others in precision and speed.更多还原
