On Periodic Scheduling and Control for Networked Systems Under Random Data Loss

چکیده
This article deals with networked control systems (NCSs) whose shared networks have limited communication capacity and are prone to data losses. Our contributions two-fold. First, we present necessary sufficient conditions on the plant controller dynamics network parameters such that there exist purely time-dependent periodic scheduling sequences under which stability of each is preserved for all admissible loss signals. Second, given a period sequence, identify plants admit static state-feedback controllers favorable presented. The main apparatus our analysis switched system representation individual in an NCS switching signals time-inhomogeneous Markov chains. involve existence sets symmetric positive definite matrices satisfy certain (in)equalities. We stabilizing their corresponding ideal between as special cases results. A numerical experiment presented demonstrate proposed techniques.

Robust Model for Networked Control System with Packet Loss
The Networked Control System in modern control widely uses to decrease the implementation cost and increasing the performance. NCS in addition to its advantages is inevitable. Nevertheless they suffer of some limitations and deficiencies. Packet loss is one of the main limitations which affect the control system in different conditions and finally may lead to system instability. For this reason...
متن کاملNeural-Smith Predictor Method for Improvement of Networked Control Systems
Networked control systems (NCSs) are distributed control systems in which the nodes, including controllers, sensors, actuators, and plants are connected by a digital communication network such as the Internet. One of the most critical challenges in networked control systems is the stochastic time delay of arriving data packets in the communication network among the nodes. Using the Smith predic...
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 کاملSampled-Data Networked Control Systems with Random Time Delay
The stability and performance of a networked control system (NCS) strongly depends on the transmission delay. However, the randomness of the transmission delay is an intrinsic property in the network communication, e.g. Ethernet. Aiming at NCS with random transmission delay, a novel control approach is proposed. The transmission delays from sensorto-controller (SC) and controller-to-actuator (C...
متن کاملKalman Filtering for networked control systems with random delay and packet loss
In this paper we study optimal estimation design for sampled linear systems where the sensors measurements are transmitted to the estimator site via a generic digital communication network. Sensor measurements are subject to random delay or might even be completely lost. We show that the minimum error covariance estimator is timevarying, stochastic, and it does not converge to a steady state. M...
