Abstract :
-The dynamic performance quality of SCDCS (Safety Critical Distributed Control System) is pertinent to its dependability. To achieve the prescribed dynamic performance, a performance index describing converged speed of system states is established based on the model-building of SCDCS that is networked on its state feedback loop. Meanwhile, a sufficient condition, which can guarantee SCDCS to be asymptotically stable under prescribed performance constraints, is derived by employment of the Lyapunov theory and the matrix measurement. Based on the condition, an algorithm for obtaining maximum allowable transfer interval is presented. Results of simulation indicate that the design method is less conservative and can not only guarantees system asymptotically stable, but also make it have desired dynamic performance.
