Non-Fragile Robust H∞ Filtering of Takagi-Sugeno Fuzzy Networked Control Systems with Sensor Failures

Abstract

The fault-tolerant robust non-fragile H∞ filtering problem for networked control systems with sensor failures is studied in this paper. The Takagi-Sugeno fuzzy model which can appropriate any nonlinear systems is employed. Based on the model, a filter which can maintain stability and H∞ performance level under the influence of gain perturbation of the filter and sensor failures is designed. Moreover, the gain matrix of sensor failures is converted into a dynamic interval to expand the range of allowed failures. And the sufficient condition for the existence of the desired filter is derived in terms of linear matrix inequalities (LMIs) solutions. Finally a simulation example is given to illustrate the effectiveness of the proposed method.

Security Control for Adaptive Event-Triggered Networked Control Systems Under Deception Attacks

“…In this section, we will offer two theorems to exhibit the main results of the adaptive event-triggered control NCSs subject to deception attacks. Theorem 1: For known λ n , λ m , matrix K, γ and scalars δ ∈ (0, 1], φ ≥ 0, ≥ 1, h > 0, the system (11) attains stable in mean square if there are symmetric matrices…”

“…The authors in [5] study the real-time continuous zero-moment point pattern generation for a humanoid robot on basis of capture point. From the point of view of control theory, different problems of NCSs have been considered and discussed, such as robust stability [6]- [10], filter design [11], [15] and state estimator design [12]. Multitudinous scholars devote themselves into the researches of NCSs and lot of achievements are available [13], [14], [17].…”

“…The problem of the H ∞ control for hybrid-driven-based networked cascade control systems in the situation of deception attacks in [20]. Considering deception attacks, the state estimators design issue for sensor networked systems is discussed in [11]. The authors in [12] propose the local design of distributed H ∞ -consensus filtering for sensor networks with deception attacks.…”

Collaborative Filtering to Predict Sensor Array Values in Large IoT Networks

“…To mention some of the existing proposals in the literature, in [ 18 ] the authors tackle imperfect transmission between the system and the controller through a mode-dependent stochastic measurement fading model. The fault-tolerant robust non-fragile filtering problem for networked control systems with sensor failures is studied in [ 19 ]. Finally, vehicle motion sensors failure is detected and recovered in [ 20 ], where the authors show that the fault detection and restoration algorithm can satisfy the control performance for each sensor failure.…”

Quantization-Mitigation-Based Trajectory Control for Euler-Lagrange Systems with Unknown Actuator Dynamics

“…However, it is non-trivial to apply the linear system-based results to control the Euler-Lagrange systems. Difficulties include not only Euler-Lagrange systems themselves are nonlinear but also they might involve different kinds of nonlinearities [ 20 , 21 ]. Please note that actuators have been regarded as an essential unit in the control systems.…”
