摘要

对水电厂非弹性和弹性五阶状态空间模型进行了状态估计。所采用的状态估计方法是基于多维插值公式的二阶多项式近似。结果表明，该方法在估计性能上优于线性卡尔曼滤波。在此基础上，提出了一种基于状态估计的水轮机转速控制方法

State estimation based LQ optimal control in application to hydro plant

The state estimation of inelastic and elastic fifth-order state-space model of hydro plant is performed. The method adopted for state estimation is based on second-order polynomial approximations of a multi-dimensional interpolation formula. It is found that the state estimation of plant by this method outperforms to linear Kalman filter in terms of estimation. Then a state estimation based linear quadratic (LQ) approach for hydro turbine speed control is presented
