In this paper, the problem of randomness attenuation is investigated for a class of MIMO semi-linear stochastic systems. To achieve this control objective, a m-block backstepping controller is designed to stabilize the closed-loop systems in probability sense. In addition, the output randomness attenuation can be achieved by optimising the design parameters using minimum entropy criterion. the effectiveness of this presented control algorithm can be verified by a given numerical example. In summary, the main contributions of this paper are characterized as follows: (1) an output feedback design method is adapted to stabilise the dynamic multi-variable semi-linear stochastic systems by block backstepping; (2) randomness of the system output is attenuated by searching the optimal design parameter based on the entropy criterion; (3) a framework of performance enhancement for stochastic systems is developed.
A design method is proposed for HFPGA-based Mealy FSMs. the method is based on transformation of collections of output functions into state variables. It allows diminishing the number of LUTs in FSM circuits in compar...

Reliable transmission of the control packets is one of the key requirements of deploying an Industrial Wireless Network (IWN) for automation purposes. the use of error-prone wireless channel, transmission of control packets having hard real-time traffic over IWN have made reliable transmission assurance highly challenging. this paper intends in addressing this challenge through reliability optimization of the hard real-time traffic transmitted over IWN. ReliaMAC is a novel scheme that is proposed to support reliable transmission of hard real-time traffic using redundancy bits added to each double MAC frame. Optimization of transmission reliability is used to identify the optimum number of nodes in an IWN that can support reliable transmission of the hard real-time traffic to a maximum extent. Network simulation results revealed the effectiveness of ReliaMAC in improving reliability of hard real-time communication on IWNs.

Cyber physical systems (CPS) is the integration of three processes: physical process, communication process and computation process. Due to the high demand of safety and real- time feature, CPS requires massive real-time spatial and temporal messages. therefore, representation and demonstration of spatio- temporal information is vital in every stage, such as specification, design, operation, control, and supervision of CPS. In this paper, we propose a method combining clock theory and RCC-8 together indicating spatio-temporal information of CPS, and we present spatio-temporal sequence diagram for change tracking under the specific scene. We take vehicle system as instance to see how the method work in description of spatio-temporal information between vehicles and vehicles, vehicles and people, vehicle and surroundings in different situations.

Cyber-physical system (CPS) emphasizes dynamic collaboration of physical process and computation process. Its high demands for real-time, safety, security, and reliability require deep integration of control, computation and communication. To achieve better performance and resource utilization in CPS, we propose a framework named cloud based cyber-physical system (CCPS) which strengthens cooperation among various layers in *** adopts closed-loop control, and makes use of cloud service for data processing in cyber-physical cloud (CPC). In order to balance real-time performance and cost of cloud service, network scheduling algorithms in various cloud models are widely discussed in this paper. In addition, we have a broad discussion on effection of tasks scheduling with respect to stability of controller in CCPS in view of time delay. Accordingly, we give simulation and comparison results of the proposed scheduling algorithms for illustration.

In this paper, an overview of the robust filtering problem is provided and the ordered weighted aggregation (OWA) operator is described. this operator is applied as a weighted average of ordered signal samples in a sliding window to produce output values of a filter. the appropriate selection of weights allows to efficiently suppress the impulsive noise. this process is similar to the moving average smoothing however this one is very sensitive to outliers. Several weighting window functions have been tested due to the ability to minimize impact. of outliers. Introducing the non-linear sorting process and attributing to the sorted samples appropriate values of weights this leads to improvement of filtering in an impulsive environment. Obtained results show the effectiveness of the proposed robust filtering method in comparison to the reference filters.

Redundancy is the main method for achieving high reliability level in networked controlsystems NCSs. It is often applied in network interfaces in order to maintain operability of communication subsystems even when faults occur. In most cases, redundant communication buses realize exactly the same functionality as the initial non-redundant bus. that makes the system more reliable but the additional throughput of the redundant buses is not exploited even if the system condition would allow it. the idea of taking advantage of that throughput had made the authors to work on multi-network interface node which on the other hand maintain the high reliability of the communication subsystem, and on the other, makes it possible to manage the additional communication resources more efficiently, and therefore increases some parameters of the communication network.
