This paper deals with the issues of reconstructibility analysis and set-observer design for Boolean control networks (BCNs). A state estimation set is considered to find the state estimation of BCNs, and a reconstructibility judgment matrix (RJM) is obtained by compact vector of state estimation set. Then, a kind of state-reconstructible tree is constructed, and algorithms are also provided to construct it. The state-reconstructible tree can categorize BCNs to be globally reconstructible, locally reconstructible, and unreconstructible. The sufficient and necessary conditions for the reconstructibility of BCNs are given. Meanwhile, the relationship between input–output trajectory and estimated state is derived. Next, with the knowledge of input–output sequence, a set-observer is designed such that the state of BCNs for any global reconstructible BCNs is uniquely determined in a finite time. Some examples are also given to illustrate the effectiveness of the proposed methods.  相似文献

The main tool used in this paper is the semi-tensor product of matrices. First, a necessary and sufficient condition is presented for the robust stability of Boolean networks based on the algebraic representation of Boolean networks with disturbance inputs. Second, the concept of one-step robust reachability is defined for Boolean control networks (BCNs) with disturbance inputs, based on which a constructive procedure is proposed for the robust stabilisation control design of BCNs.

For some practical systems modeled by discrete-event systems (DESs), the event observation mechanism may be no longer static/fixed due to sensor faults/failures, packet loss, and/or measurement uncertainties. It is required to redefine the observations of events. Therefore, it is interesting to reconsider the opacity in the context of abnormal conditions as mentioned. In this paper, we extend notions of initial-state opacity (ISO), current-state opacity (CSO), and initial-and-final-state opacity (IFSO) in a standard setting to an advanced framework of nondeterministic observations (i.e., the event-observation mechanism is state-dependent and nondeterministic) by taking the output-observation-equivalence instead of the natural projection-equivalence into account. To efficiently verify them, we construct three new matrix-based information structures in this advanced framework called an initial-state estimator, a current-state estimator, and an initial-and-final-state estimator using the Boolean semi-tensor product (BSTP) theory. Accordingly, the matrix-based criteria for verifying these three types of opacity are given, respectively. Computational complexity analysis as well as illustrative examples are also provided for the proposed results.  相似文献

This paper investigates the Morgan''s problem of Boolean control networks. Based on the matrix expression of logical functions, two key steps are proposed to solve the problem. First, the Boolean control network is converted into an output-decomposed form by constructing a set of consistent output-friendly subspaces, and a necessary and sufficient condition for the existence of the consistent output-friendly subspaces is obtained. Secondly, a type of state feedback controllers are designed to solve the Morgan''s problem if it is solvable. By solving a set of matrix equations, a necessary and sufficient condition for converting an output-decomposed form to an input-output decomposed form is given, and by verifying the output controllability matrix, the solvability of Morgan''s problem is obtained.  相似文献

In the literatures, to design state feedback controllers to make the response Boolean network synchronise with the drive Boolean network is rarely considered. Motivated by this, feedback control design for the complete synchronisation of two coupled Boolean networks is investigated in this paper. A necessary condition for the existence of a state feedback controller achieving the complete synchronisation is established first. Then, based on the necessary condition, the feedback control law is proposed. Finally, an example is worked out to illustrate the proposed design procedure.  相似文献

Using the semi-tensor product method, this paper investigates the algebraic formulation and strategy consensus for a class of networked evolutionary games (NEGs) with ‘unconditional imitation updating rule’, and presents a number of new results. First, the given NEG is converted to an algebraic form via the semi-tensor product method, and an algorithm is established to obtain the algebraic expression of the considered game. Second, based on the algebraic form, the behaviours of the players in the given evolutionary games are analysed, and some meaningful results are presented. Finally, the strategy consensus problem is considered by adding a pseudo-player to the game, and a free-type control sequence is designed to make the given NEG reach strategy consensus. The study of an illustrative example shows that the new results obtained in this paper work very well.  相似文献
