The current topology schemes of heavy ion accelerator power supply have serious pollution to the power grid caused by low power factor of the grid side. Considering the characteristics of adjustable power factor and bidirectional energy transfer of the matrix converter, the possibility of which applied to the accelerator DC power supply is studied and three kinds of backup topology schemes including the preceding regulated matrix rectifier (MR) are proposed in this article. Given the actual situation of accelerator power supply, research has been focused on the modulation strategy suitable for the topology of the preceding regulated MR and simulation validation. Based on simulation of the preceding regulated MR scheme, a matrix power prototype is developed. A power factor tester is utilized to test grid side power factor. According to the experimental results, it is prospectively feasible to apply the preceding regulated MR topology to accelerator DC power supply, with excellent performance of the grid side.

The minimum‐energy formation tracking design and analysis problems for interconnected networks with distributed tracking protocols are addressed, where the effects of the total energy restriction and the interaction silence on the formation tracking are discussed, respectively. The key characteristic of this article is that the value of the energy restriction is required to be minimum, while the guaranteed‐cost tracking strategy and the energy‐constraint tracking strategy cannot ensure the minimum property of the total energy restriction. For interconnected networks without the interaction silence, sufficient conditions for minimum‐energy formation tracking are presented, whose effectiveness can be checked by the optimization procedure associated with the generalized eigenvalue method. Then, for interconnected networks with the interaction silence, by constructing the specific constraint associated with the maximum silent rate and two inhibition parameters, sufficient conditions for minimum‐energy formation tracking are proposed. Finally, numerical examples are shown to illustrate the efficacy of main results.

“…In References 24 and 25, a secure impulsive consensus control strategy was investigated to obtain ultimate uniformly bounded consensus for the MASs suffering from false data injection attacks, and the upper bounds of the consensus errors were given. Moreover, the design and analysis problems of secure formation and consensus are addressed respectively for MASs with the intermittent communication in References 26‐29, and some meaningful results are given. In the above works, it was assumed that weights of communication links are time‐invariant or the communication topology is deterministic.…”

The secure consensualization for leaderless nonlinear multiagent systems with communication link attacks is realized in a fully distributed manner in a certain sense that the gain matrix design do not depend on the communication topology.A new virtual reference state estimator is proposed for each agent to estimate the common tracking state, which can adaptively adjust coupling strengths to counteract the influence of communication link attacks. Then, by the Lipschitz condition and the special structure property of the time-varying nonsingular transformation matrix, the influence of the Lipschitz nonlinearity on secure consensus is linearized, and a design approach of the secure consensus control gain is given on the foundation of the linear matrix inequality. Finally, a numerical example is provided to demonstrate the effectiveness of theoretical results. K E Y W O R D Scommunication link attacks, fully distributed control, Lipschitz nonlinearity, multiagent system, secure consensus INTRODUCTIONRecently, coordinated control of multiagent systems (MASs) has been attached great importance because of its extensive applications in many fields, including consensus/formation control of multiple robots, 1-4 satellite attitude coordination control, 5 and synchronization of smart power grids 6-8 and wireless sensor networks 9,10 and so forth. Fully distributed consensus control is one of the important topics in the above fields, which needs that all agents reach agreement on some interesting variables by constructing the consensus protocol in a fully distributed manner. Some fully distributed consensus protocols and important conclusions were shown in References 11-15, where the influence of the communication link attack or fault was not considered. With the rapid advancement of artificial intelligence and information technology, the communication link attack is an important threat for MASs. Attacks on the communication link can block the communication channels among agents, and can cause the data information transmitted in the communication topology to be unavailable or invalid, which may seriously damage the consensus properties of the whole system. This motivates researchers to study secure consensus control (SCC) for MASs with communication link attacks.
