Abstract ：
This paper studies a dual objective control problem for an energy storage system (ESS) consisting of multiple independently-controlled energy storage units (ESUs). The power output of the entire ESS is designed to meet its reference, and meanwhile the state-of-energy (SOE) of all the ESUs maintains to be balanced. In practice, the communication among ESUs might be unreliable and thus is modeled by jointly connected switching networks. By making use of the so-called Generalized Krasovskii-LaSalle Theorem together with a novel two-step recursive analysis method, it is rigorously proven that the dual objective control problem subject to jointly connected switching networks can be solved by a consensus-based distributed control algorithm.

Abstract ：
This article solves the dual objective control problem for an energy storage system by distributed aperiodic sampled-data controller under both connected static network and jointly-connected switching network. The proposed sample-and-hold controller is composed of the leaderless consensus algorithm, which aims at state-of-energy balancing, and the leader-following distributed observer, which aims at reference power tracking. By resorting to the generalized Krasovskii-LaSalle theorem, it is proven that the closed-loop system is uniformly exponentially stable using the so-called limiting solution. There are two distinguished features of the proposed control scheme. First, the designs of the leaderless consensus algorithm and the leader-following distributed observer can be accomplished independently. Second, the effectiveness of the control law can be guaranteed by properly tuning the feedback gains even for some extreme cases of drastic changes on sensing and sampling. Comprehensive simulation results are shown to examine the performance of the proposed control implement.

Abstract ：
The solvability of certainty equivalence control problems for discrete-time multiagent systems over uniformly jointly connected switching networks relies on the stability/attractivity analysis for a class of perturbed switched systems with respect to a set of switching signals. To tackle this issue, in this article, a novel systematic and unified framework is established consisting of three key stability/attractivity results. First, the uniform global exponential stability for two dual cases of the nominal dynamics is analyzed in a unified way by checking the weak zero-state detectability from the limiting systems. Second, the uniform global exponential attractivity of the perturbed switched systems accommodating both first-order and zero-order time-varying perturbations is studied without resorting to any Lyapunov function for the entire perturbed switched systems. Third, the uniform global kappa-exponential stability for a class of cascaded switched systems is investigated. These stability/attractivity results together lay the foundation to thoroughly solve two kinds of typical certainty equivalence control problems, and also improve two specific cooperative control designs. Moreover, a relaxed dwell-time condition is considered, which makes the obtained results tolerable in the extreme case of instantaneous link failure and restoration. Finally, the control performances are shown by numerical simulations.

Abstract ：
In [Chen et al., 2020], the third author and other coauthors studied global dynamics of the following system: {(x)overdot = y - [b(1)x - b(2)/2 (vertical bar x + 1 vertical bar - vertical bar x - 1 vertical bar)], (y)overdot = - [b(3)x + b(2)/2 (vertical bar x + 1 vertical bar - vertical bar x - 1 vertical bar) - b(4]), in the parameter region {( b(1), b(2), b(3), b(4)) is an element of R-4 : b(2) < 0, b(4) not equal 0}. To study completely the piecewise linear system, we consider the parameter region {( b(1), b(2), b(3), b(4)) is an element of R-4 : b(2) > 0, b(4) not equal 0} in this paper. Firstly, we study the local dynamics, such as the bifurcations of equilibria (including the equilibrium at infinity). Secondly, the number and stability of limit cycles are studied completely. Then, we analyze the existence of upper and lower saddle connections and homoclinic loops. Moreover, we show that there are no heteroclinic loops in this parameter region. Finally, we give the bifurcation diagram and all global phase portraits on the Poincare disc are given as well as some numerical examples.

Abstract ：
Chen [2016a, 2016b] studied global dynamics of the Filippov systems <(x)double over dot> + (alpha + beta x(2))(x)over dot + x +/- sgn(x) = 0, respectively. To study the global dynamics of <(x)double over dot>+(alpha+beta x(2))(x)over dot +/- x +/- sgn(x) = 0 completely, since the dynamics of <(x)double over dot>+(alpha+beta x(2))(x)over dot-x-sgn(x) = 0 is very simple, we are only interested in the global dynamics of <(x)double over dot>+(alpha+beta x(2))(x)over dot - x + sgn(x) = 0 in this paper. Firstly, we use Briot-Bouquet transformations and normal sector methods to discuss these degenerate equilibria at infinity. Secondly, we discuss the number of limit cycles completely. Then, the sufficient and necessary conditions of existence of the heteroclinic loop are found. To estimate the upper bound of the heteroclinic loop bifurcation function on parameter space, a result on the amplitude of a unique limit cycle of a discontinuous Lienard system is given. Finally, the complete bifurcation diagram and all global phase portraits are presented. The global dynamic property of system <(x)double over dot>+(alpha+beta x(2))(x) over dot-x+sgn(x) = 0 is totally different from systems <(x)double over dot>+(alpha+beta x(2))(x)+x +/- sgn(x) = 0.
