Stability Analysis and Control of Several Classes of Logical Dynamic Systems and the Applications in Game Theory
With the rapid development of complex networks, logical dynamic systems have been
commonly used mathematical models for simulating Genetic Regulatory Networks (GRNs)
and Networked Evolutionary Games (NEGs), which have attracted considerable attention
from biology, economy and many other fields. By resorting to the Semi-Tensor Product
(STP) of matrices, logical dynamic systems can be equivalently converted into discrete time
linear systems with algebraic forms. Based on that, this thesis analyzes the stability and
studies the control design problems of several classes of logical dynamic systems. Moreover,
the obtained results are applied to investigate the control and optimization problems of
NEGs. The main results of this thesis are the following.
• The stability and event-triggered control for a class of k-Valued Logical Networks
(KVLNs) with time delays are studied. First, some necessary and sufficient con-
ditions are obtained to detect the stability of Delayed k-Valued Logical Networks
(DKVLNs). Second, the global stabilization problem under event-triggered control is
considered, and some necessary and sufficient conditions are presented for the sta-
bilization of Delayed k-Valued Logical Control Networks (DKVLCNs). Moreover, an
algorithm is proposed to construct all the event-triggered state feedback controllers
via antecedence solution technique.
• The robust control invariance and robust set stabilization problems for a class of Mix-
Valued Logical Control Networks (MVLCNs) with disturbances are studied. First, a
calculation method for the Largest Robust Control Invariant Set (LRCIS) contained
in a given set is introduced. Second, based on the Robust Control Invariant Subset
(RCIS) obtained, the robust set stabilization of MVLCNs is discussed, and some
new results are presented. Furthermore, the design algorithm of time-optimal state
feedback stabilizers via antecedence solution technique is derived.
• The robust set stability and robust set stabilization problems for a class of Probabilis-
tic Boolean Control Networks (PBCNs) with disturbances are studied. An algorithm
to determine the Largest Robust Invariant Set (LRIS) with probability 1 of a given
set for a Probabilistic Boolean Network (PBN) is proposed, and the necessary and
sufficient conditions to detect whether the PBN is globally finite-time stable to this
invariant set with probability 1 are established. Then, the PBNs with control inputs
are considered, and an algorithm for LRCIS with probability 1 is provided, based on
which, some necessary and sufficient conditions for finite-time robust set stabiliza-
tion with probability 1 of PBCNs are presented. Furthermore, the design scheme of
time-optimal state feedback stabilizers via antecedence solution technique is derived.
• The stabilization and set stabilization problems for a class of Switched Boolean Con-
trol Networks (SBCNs) with periodic switching signal are studied. First, algebraic
forms are constructed for SBCNs with periodic switching signal. Second, based on
the algebraic formulations, the stabilization and set stabilization of SBCNs with peri-
odic switching signal are discussed, and some new results are presented. Furthermore,
constructive procedure of open loop controllers is given, and the design algorithms of
switching-signal-dependent state feedback controllers via antecedence solution tech-
nique are derived.
• The dynamics and control problems for a class of NEGs with time-invariant delay in
strategies are studied. First, algebraic forms are constructed for Delayed Networked
Evolutionary Games (DNEGs). Second, based on the algebraic formulations, some
necessary and sufficient conditions for the global convergence of desired strategy pro-
file under a state feedback event-triggered controller are presented. Furthermore, the
constructive procedure and the number of all valid event-triggered state feedback
controllers are derived, which can make the game converge globally.
• The evolutionary dynamics and optimization problems of the networked evolutionary
boxed pig games with the mechanism of passive reward and punishment are studied.
First, an algorithm is provided to construct the algebraic formulation for the dynamics
of this kind of games. Then, the impact of reward and punishment parameters on the
final cooperation level of the whole network is discussed

Filtering for nonlinear genetic regulatory networks with stochastic disturbances
In this paper, the filtering problem is investigated for nonlinear genetic regulatory networks with stochastic disturbances and time delays, where the nonlinear function describing the feedback regulation is assumed to satisfy the sector condition, the stochastic perturbation is in the form of a scalar Brownian motion, and the time delays exist in both the translation process and the feedback regulation process. The purpose of the addressed filtering problem is to estimate the true concentrations of the mRNA and protein. Specifically, we are interested in designing a linear filter such that, in the presence of time delays, stochastic disturbances as well as sector nonlinearities, the filtering dynamics of state estimation for the stochastic genetic regulatory network is exponentially mean square stable with a prescribed decay rate lower bound beta. By using the linear matrix inequality (LMI) technique, sufficient conditions are first derived for ensuring the desired filtering performance for the gene regulatory model, and the filter gain is then characterized in terms of the solution to an LMI, which can be easily solved by using standard software packages. A simulation example is exploited in order to illustrate the effectiveness of the proposed design procedures
