In the industrial process,the systems may be to have time-delay and the elements in it may be to fail with the increase in run-time,which may yield the whole system's performance and stability getting worse.So,it is particularly important to study fault-tolerant control for descriptor linear systems with delay.The problem of fault-tolerant H_∞control via static output feedback is considered for a class of discrete descriptor linear time-delay systems whose sensors satisfy a continuous fault model.Based on Lyapunov stability theory and linear matrix inequality approach,two approchaes to design a memoryless static output feedback and a memory static output feedback,guaranteeing that the resultant closed-loop system is admissible and its H_∞norm is bounded by a pre-specified positive number is presented,respectively.The static output feedbacks are constructed by a solving a group of linear matrix inequalities.A numerical example illustrates the validity of the proposed approach.
