| 中文摘要 |
| 本文针对同时含未建模不确定性和执行器失效的系统,利用Riccati方程和Lyapunov稳定性定理给出了鲁棒控制器设计方法。通过在每个控制回路中嵌入增益,结合Riccati方程中加权矩阵Q和R的适当选取,本文所给出的控制器在正常和某些冗余执行器失效情况下,皆对系统中普遍存在的不确定具有鲁棒稳定性。 |
| 英文摘要 |
| A design method of robust controller of multivariable system with uncertainty and actuator failures is presented by using Riccati equation and Lyapunov stability principle. It is proved that the robust closed-loop stability can be maintained by inserting appropriate constant gains in the control loops and by properly selecting weighting matrix Q and R of Riccati equation. |
