针对电力系统元件非线性微分-代数子系统模型,本文提出一种新算法研究其逆系统控制问题.所提出的新算法不需要对控制输出及其高阶导数做复杂的变换,具有更好的应用性.本文的逆系统控制方法主要分为两步：第1步,利用所提出的新算法来判断被控元件的可逆性,若可逆,则基于状态反馈与动态补偿,构造出元件的α阶积分右逆系统,实现复合系统的线性化和解耦;第2步,利用线性控制的理论和方法设计闭环控制器,使得元件被控对象满足期望的性能指标.最后按照本文所提出的方法,研究了多机电力系统的分散非线性汽门控制问题.仿真结果验证了本文所提方法的有效性.

英文摘要：

For power system components based on nonlinear differential algebraic equations subsystems,a novel al-gorithm is proposed to study their inverse system control problem.This algorithm does not need complex transforma-tions of controlled output vector and its high order derivative vector,which means better applicability.The procedureof inverse system controller design can be divided into two parts.First,to judge the invertibility of the controlled sub-system using the proposed algorithm.If it is invertible,an α-order integral right inverse system can be constructed bystate-feedback and dynamic compensation,with which the decoupling and linearization of the composed systems areachieved.Second,various linear control theories and methods are applied to achieve the desired closed-loop perform-ance.A decentralized nonlinear inverse valve controller is designed for multi-machine power systems based on theproposed method in this paper and the simulation results illustrate its validity.
