Stabilization and Performance Analysis for Networked Flight Control System with Random Time Delays via a LMI Gridding Approach
نویسندگان
چکیده
The use of avionics networks for flight control system results in a reduced aircraft weight, system installation, integration and maintenance costs as well as an improved airborne system performance and flexibility. This paper studies the stability and control design problems with performance analysis for networked flight control systems (NFCS) with random time delays by modeling NFCS as a discrete-time switched linear system. Sufficient conditions are given for asymptotical stability and exponential stability of proposed NCS model and state feedback controller is designed via linear matrix inequality (LMI) approach. The bound of decay rate of the system is obtained by solving a LMI optimization problem. Gridding approach is introduced to guarantee the feasibility of proposed LMIs. Illustrative examples are presented to demonstrate the effectiveness of the proposed method and control performance with decay rate is analyzed based on the simulation results. Copyright © 2013 IFSA.

Design of Observer-based H∞ Controller for Robust Stabilization of Networked Systems Using Switched Lyapunov Functions
In this paper, H∞ controller is synthesized for networked systems subject to random transmission delays with known upper bound and different occurrence probabilities in the both of feedback (sensor to controller) and forward (controller to actuator) channels. A remote observer is employed to improve the performance of the system by computing non-delayed estimates of the sates. The closed-loop s...
متن کاملStabilization of Networked Control Systems with Variable Delays and Saturating Inputs
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. Two different techniques are employed to incorporate actuator...
متن کاملTime Delay and Data Dropout Compensation in Networked Control Systems Using Extended Kalman Filter
In networked control systems, time delay and data dropout can degrade the performance of the control system and even destabilize the system. In the present paper, the Extended Kalman filter is employed to compensate the effects of time delay and data dropout in feedforward and feedback paths of networked control systems. In the proposed method, the extended Kalman filter is used as an observer ...
متن کاملModelling and Compensation of uncertain time-delays in networked control systems with plant uncertainty using an Improved RMPC Method
Control systems with digital communication between sensors, controllers and actuators are called as Networked Control Systems (NCSs). In general, NCSs encounter with some problems such as packet dropouts and network induced delays. When plant uncertainty is added to the aforementioned problems, the design of the robust controller that is able to guarantee the stability, becomes more complex. In...

In this paper, the problems of robust stabilization and$H_{infty}$ control for uncertain stochastic systems withmultiple time delays represented by the Takagi-Sugeno (T-S) fuzzymodel have been studied. By constructing a new Lyapunov-Krasovskiifunctional (LKF) and using the bounding techniques, sufficientconditions for the delay-dependent robust stabilization and $H_{infty}$ control scheme are p...
