چکیده
Abstract: In this paper, the problem of delay-dependent stabilization for singular systems with multiple internal and external incommensurate constant point delays is investigated. The condition when a singular system subject to point delays is regular independent of time delays is given and it can be easily test with numerical or algebraic methods. Based on LyapunovKrasovskii functional approach and the descriptor integral-inequality lemma, a sufficient condition for delay-dependent stability is obtained. The main idea is to design multiple memoryless state feedback control laws such that the resulting closed-loop system is regular independent of time delays, impulse free, and asymptotically stable via solving a strict linear matrix inequality (LMI) problem. An explicit expression for the desired memoryless state feedback control laws is also given. Finally, a numerical example illustrates the effectiveness and the availability for the proposed method.

In this paper, improved conditions for the synthesis of static state-feedback controller are derived to stabilize networked control systems (NCSs) subject to actuator saturation. Both of the data packet latency and dropout which deteriorate the performance of the closed-loop system are considered in the NCS model via variable delays.

متن کاملDelay-dependent Stabilization of Uncertain Singular Systems with Multiple State Delays
The problem of delay-dependent robust stabilization for singular systems with multiple state delays is investigated. Firstly, without using any model transformation and bounding technique for cross terms, a delay-dependent stability criterion is given to ensure that the singular system is regular, impulse free and stable. Based on this criterion, the state feedback controller is also given, whi...
