IEEE International Conference on Networking, Sensing and control

This paper proposes a concurrency strategy based on timed-transition Petri net for scheduling flexible manufacturing system (FMS). Combined with the heuristic function, prior search algorithms explore only one transition during each execution, which brings in many redundancy states for the expending procedure. In this paper, we prove that firing some non-conflicting transitions simultaneously can also achieve an optimal schedule. This can help the search algorithm explore deeper successor states and avoid many unnecessary intermediate states. As a result, the search effort can be reduced apparently while the optimality of result is still guaranteed. The experimental results show that the proposed concurrency strategy performs better than the reported methods.

This paper employs a logistical regression classifier for combining particle swarm optimizer and local optimizer to solve dynamic optimization problems. It achieves the ability of automatic transition from global optimizer to local optimizer according to the state of solutions. The particle swarm optimizer is used to globally search for a good approximation of the solution and then SQP is applied as the local optimizer for quickly converging to the optima. Experimental results on two complex chemical processes demonstrate that the proposed method can get comparable and even better results than the existed methods in precision and especially in function evaluations.

In this paper a comprehensive introduction for modeling and control of networked evolutionary games （NEGs） via semi-tensor product （STP） approach is presented. First, we review the mathematical model of an NEG, which consists of three ingredients： network graph, fundamental network game, and strategy updating rule. Three kinds of network graphs are considered, which are i） undirected graph for symmetric games; ii） directed graph for asymmetric games, and iii） d-directed graph for symmetric games with partial neighborhood information. Three kinds of fundamental evolutionary games （FEGs） are discussed, which are i） two strategies and symmetric （S-2）; ii） two strategies and asymmetric （A-2）; and iii） three strategies and symmetric （S-3）. Three strategy updating rules （SUR） are introduced, which are i） Unconditional Imitation （UI）; ii） Fermi Rule（FR）; iii） Myopic Best Response Adjustment Rule （MBRA）. First, we review the fundamental evolutionary equation （FEE） and use it to construct network profile dynamics （NPD）of NEGs. To show how the dynamics of an NEG can be modeled as a discrete time dynamics within an algebraic state space, the fundamental evolutionary equation （FEE） of each player is discussed. Using FEEs, the network strategy profile dynamics （NSPD） is built by providing efficient algorithms. Finally, we consider three more complicated NEGs： i） NEG with different length historical information, ii） NEG with multi-species, and iii） NEG with time-varying payoffs. In all the cases, formulas are provided to construct the corresponding NSPDs. Using these NSPDs, certain properties are explored. Examples are presented to demonstrate the model constructing method, analysis and control design technique, and to reveal certain dynamic behaviors of NEGs.

The vast majority of strategies aimed at controlling contagion processes on networks consider the connectivity pattern of the system either quenched or annealed. However, in the real world, many networks are highly dynamical and evolve, in time, concurrently with the contagion process. Here, we derive an analytical framework for the study of control strategies specifically devised for a class of time-varying networks, namely activity-driven networks. We develop a block variable mean-field approach that allows the derivation of the equations describing the coevolution of the contagion process and the network dynamic. We derive the critical immunization threshold and assess the effectiveness of three different control strategies. Finally, we validate the theoretical picture by simulating numerically the spreading process and control strategies in both synthetic networks and a large-scale, real-world, mobile telephone call data set.

Wireless links provides great convenience in node deployment. But its limited bandwidth brings challenge for large volume transmission tasks. Compressive sensing (CS) is a promising solution for this problem. In this paper, we present a CS based wireless sensor network framework for acoustic signal acquisition, which can significantly reduce acoustic signal data volume without affecting its quality. The framework consists of Transmitter, Receiver and Terminal, all combined to complete tasks including signal receiving, compressive sampling, wireless sending and receiving, and signal recovery. A experimental testbed is implemented using FPGA and Zig Bee chips. The results show that these signals can be well recovered with negligible norm error. It also indicates that using this framework can significantly reduce the total volume of signal acquisition.

A Partial-state Observer for a Class of MIMO Nonlinear systems

In this paper, we consider input-affine invertible MIMO nonlinear systems which can be transformed into a special normal form by means of the structure algorithm. The normal form highlights a partial state, a subset of state variables, which plays in this setting a role similar to that of the outputs and its derivatives in a SISO system. It is shown that, if a system in this class can be asymptotically stabilized by means of a static feedback from that partial state, then semiglobal stabilization can be achieved via dynamic feedback driven by the output of the system. The dynamic feedback in question is based a (non–trivial) extension to MIMO systems of the standard high–gain observer.

This paper investigates the modeling and H∞ composite control of the coupled hysteretic dynamics in a piezoelectric micro-displacement system (PMS). First, the coupled multi-field hysteretic dynamics with physical meanings is presented for PMS. Next, the composite control analysis of the hysteretic dynamics is proposed. Then, a H∞ synthesis controller is designed by using the simplified hysteretic dynamics. To enhance the H∞ performance, the inversion-based feedforward compensation is augmented. The proposed H∞ feedback control and the inversion-based feedforward can be designed separately. Finally, the experimental studies are provided to demonstrate the proposed H∞ composite control approach.
