    摘要:

    時(shí)滯是許多工業(yè)系統的固有特性,會(huì )導致系統控制性能的下降,甚至影響系統穩定,而在實(shí)際系統中,有限時(shí)間系統的特性更值得關(guān)注。針對上述情況,對一類(lèi)具有時(shí)滯的馬爾可夫跳變系統有限時(shí)間控制器設計的問(wèn)題進(jìn)行了研究。把轉移概率完全已知的條件放寬至部分未知的更一般情形,采用自由權重的方法,保證所得的線(xiàn)性矩陣不等式具有更小的保守性。首先,給出馬爾科夫跳變系統有限時(shí)間有界性、有限時(shí)間 H無(wú)窮有界性的判定準則。然后,通過(guò)對線(xiàn)性矩陣不等式(LMIs)求解,獲得狀態(tài)觀(guān)測器和狀態(tài)反饋控制器的增益矩陣。最后,仿真實(shí)例驗證所提算法的有效性。

    Abstract:

    Delay is an inherent characteristic of many industrial systems, which can lead to the decline of system control performance and even affect the stability of the system. In practical systems, the characteristics of finite-time systems deserve more attention. In view of the above situation, the design of finite-time controller for a class of Markov jump systems with time-delay is studied. By relaxing the condition that the transition probability is fully known to a more general case where the transition probability is partially unknown, the free weight method is adopted to ensure that the obtained linear matrix inequalities are less conservative. Firstly, the criteria of finite-time boundedness and finite-time Boundedness for Markov jumping systems are given. Then, the gain matrix of the state observer and the state feedback controller is obtained by solving the linear matrix inequality (LMIs). Finally, a simulation example is given to verify the effectiveness of the proposed algorithm.
