Fuzzy Observer-Based Robust H∞ Guaranteed Cost Fault-Tolerant Design for Nonlinear NCS

A fault-tolerant control problem of robust H ∞ guaranteed is addressed for nonlinear networked control systems (NNCS) with network-induced delay and packed dropout based on T-S fuzzy model. The delay-dependent sufficient condition against actuator failures is gived by employing state observer and state feedback control strategy. Observer-based controller gain and state feedback controller gain can be obtained and optimized. An example is used to illustrate the effectiveness and feasibility of proposed approach.
