This paper investigates the receding horizon state estimation for the linear discrete-time system with multi-channel observation delays. The receding horizon estimation is designed by the reorganized observation technique and the linear unbiased estimation method. A batch form and an recursive form for receding horizon estimation are developed based on the reorganized measurements. The estimation...
This paper designs a boundary controller for a reaction-advection-diffusion equation on the cylindrical surface with input delay. We introduce a transport partial differential equation (PDE) to remove the input delay by transforming the time delay into a spatial travelling. Then the system with time delay turns to a cascade system composed of two PDEs without delay. For the cascade system, we design...
In this paper, the problem of positive observer design of linear positive systems is studied. This paper aims to providing new design approaches for positive observers of linear positive systems. First, an efficient continuous-time positive observer design approach is proposed by using linear programming such that the observer error system is exponentially stable. Then, the results are also extended...
In the process of China's automated production, the upgrading and networking of old infrastructures becomes one of the key issues. With large quantity, numerous varieties and wide distribution, these infrastructures brings complex design work and high cost to network them into fieldbus, which greatly hamper the building of intelligent factories. This paper proposed an industrial-control solution to...
Multi-model adaptive preview control for state-delay system with unknown parameters is considered in this paper. State-delay system with unknown parameters is changed into a general system without state delay in form by using discrete lifting techniques. Then, according to preview control theory, augmented error system without state delay is obtained. Based on multi-model adaptive preview control...
Control system based on traditional PID (TPID) algorithm is one of the most effective solutions in modern industries. In the meantime, the fuzzified PID (FPID) controller has also been researched in multiple disciplines for its better robustness and transient performance. This paper is aimed to improve a versatile procedure to determine the fuzzy I/O scaling factors automatically. First, it takes...
In this paper, the problem of stability for complex-valued neural networks involving both discrete and distributed delays is considered. Assuming that the activation function can be separated into its real and imaginary part, a sufficient condition is proposed for the asymptotical stability of the addressed neural networks by employing some analysis techniques. Finally, a numerical example is presented...
When designing a controller in DC Microgrid, normally the communication delay, which may cause system instability, has not been taken into account. In this paper, the effect of communication delay on system stability is studied based on a distributed control strategy. To obtain a less conservative condition for system stability, the delay-dependent stability is analyzed. In the case of time-invariant...
Aiming at the rapid scheduling of collaborative detection traffic in Internet of things (IOT), a cooperative detection scheduling model about the bottom of IOT was designed in the paper; the model prioritized the traffic data of the sensing layer through the local scheduler of the collaboration layer, then an improved weighted round robin (IWRR) method was used to schedule the traffic data, the IWRR...
This paper investigates the consensus of multiagent systems with parameter uncertainty and control gain error. In order to decrease the communication cost, the impulsive consensus protocol is derived to achieve the consensus. Due to the inevitable disturbance, parameter uncertainty and control gain error in multi-agent systems are considered simultaneously. One necessary simulation is finally given...
This work is devoted to the admissibility analysis for singular time-delay systems by using delta operator approach. By estimating the delay term with a two-term approximation, the singular system in delta operator domain is transformed into an interconnection of a time-invariant subsystem with constant delay and a uncertain one. By resorting to the input-output approach, a delay-range-dependent admissibility...

Firstly, The EDP is transformed to the average consensus problem and the ratio consensus protocol is utilized to address the average consensus problem over unbalanced directed topology. The proposed algorithm is implemented in a fully distributed fashion without using any global...
This paper addresses the problem of the fault detection problem for discrete-time Markovian jump systems under an event-triggered scheme. The event-triggered scheme from the plant to the fault detection filter is utilized to reduce the frequency of transmission. Our attention is focused on the design of a fault detection filter such that the residual system is stochastically stable and satisfies some...
