【摘要】:控制可重構(gòu)性本質(zhì)上度量了不利條件下被控系統(tǒng)剩余的能控性。鑒于此,本文以衛(wèi)星姿態(tài)控制系統(tǒng)為研究對象,研究了故障系統(tǒng)可重構(gòu)性和剩余能控性之間的關(guān)系,提出了一種基于能控性格萊姆矩陣的可重構(gòu)評價(jià)方法。首先,對標(biāo)準(zhǔn)能控性格萊姆矩陣的局限性進(jìn)行了分析:由于該方法需要求解李雅普諾夫方程,故只適用于穩(wěn)定系統(tǒng)或特征值和不為0的非穩(wěn)定系統(tǒng);然后,引入經(jīng)驗(yàn)?zāi)芸匦愿袢R姆矩陣,不用直接求解李雅普諾夫方程即可獲取格萊姆矩陣,使得該方法可擴(kuò)展應(yīng)用于衛(wèi)星姿態(tài)控制系統(tǒng);其次,考慮到經(jīng)驗(yàn)格萊姆矩陣計(jì)算量大,采用精細(xì)積分方法提高了計(jì)算效率;最后,通過3個(gè)仿真算例,驗(yàn)證了本文所提方法的有效性和正確性。
[Abstract]:Control reconfiguration essentially measures the remaining controllability of the controlled system under unfavorable conditions. In view of this, the relationship between reconfiguration and residual controllability of the fault system is studied, and a reconfigurable evaluation method based on controllable character Lym matrix is proposed. Firstly, the limitations of the standard controllable character Lyme matrix are analyzed: the method is only suitable for stable systems or eigenvalues and non-stable systems with non-zero because of the need to solve Lyapunov equation. With the introduction of experiential controllable character Lyme matrix, the Grimm matrix can be obtained without directly solving Lyapunov equation. The method can be extended to satellite attitude control system. Secondly, considering the large amount of computation of empirical Grimm matrix, The precision integration method is used to improve the computational efficiency. Finally, the validity and correctness of the proposed method are verified by three simulation examples.
