摘要：The automatic projection filter is a recently developed numerical method for projection filtering that leverages sparse-grid integration and automatic differentiation. However, its accuracy is highly sensitive to the accuracy of the cumulant-generating function computed via the sparse-grid integration, which in turn is also sensitive to the choice of the bijection from the canonical hypercube to the state space. In this article, we propose two new adaptive parametric bijections for the automat...

摘要：This article investigates the stabilization and optimal control problems for Markov jump linear system (MJLS) with multiplicative noises and input delays. By overcoming the substantive difficulty resulting from the invalidity of the separation principle, we provide a complete solution to the addressed problems by means of 1) necessary and sufficient solvability, and the analytical formula on optimal finite horizon control in line with a generalized coupled difference Riccati equation; and 2) n...

摘要：An output feedback stochastic model predictive control is proposed in this article for a class of stochastic linear discrete-time systems, in which the uncertainties from external disturbance, measurement noise, and initial state estimation error are all considered. Particularly, the support sets of the uncertainties are unbounded and the distributions are not exactly known. Based on distributionally robust optimization, a deterministic convex reformulation is derived for handling chance const...

摘要：We show that the pair (speed, rotor position) of interior permanent magnet synchronous motors is not globally observable, and the number of all indistinguishable pairs is at most four, an invariant independent of any parameter. This result follows as a corollary by virtue of characterizing the observability condition as a special restricted form of the injectivity of a family of polynomials via immersion. The field-oriented control (FOC), which causes the collapse of at most two indistinguisha...

摘要：This work proposes a reachability approach to characterize how disturbances and safety propagate in a mixed platoon, i.e., a platoon with human-driven vehicles followed by a single automated vehicle. We look at the behavior of the leading vehicle as a unit-energy disturbance and study how this energy propagates along the states and the outputs of the system. To describe the propagation, we make use of ellipsoidal sets, and give conditions based on linear matrix inequalities to describe inclusi...

摘要：This article investigates the flocking control of a swarm with a malicious agent that falsifies its controller parameters to cause collision, division, and escape of agents in the swarm. A novel geometric flocking condition is established by designing the configuration of the malicious agent and its neighbors, under which we propose a hierarchical geometric configuration-based flocking control method. To help detect the malicious agent, a parameter estimate mechanism is also provided. The prop...

摘要：A controller synthesis method for state- and input-constrained nonlinear systems is presented that seeks continuous piecewise affine (CPA) Lyapunov-like functions and controllers simultaneously. Nonconvex optimization problems are formulated on triangulated subsets of the admissible states that can be refined to meet primary control objectives, such as stability and safety, alongside secondary performance objectives. A multistage design is also given that enlarges the region of attraction (ROA...

摘要：Multiagent consensus systems are commonly studied in regard to their scalability and performance. Their scalability relies heavily on the underlying communication system and its connectivity. While it is possible to generate a random graph, which exhibits almost surely good connectivity even with a large number of agents, in a plug-and-play setting, where agents should be able to connect and disconnect with minimal interruption, the generation of a new communication network, i.e., graph, each ...

摘要：The vulnerability analysis of remote state estimation with batch-data detectors is investigated in this article. The considered scenario is that sensors measure the process state and transmit measurements to the remote end via wireless networks, where the yielded innovation may be altered by an adversary in an affine form. At the remote end, a detector utilizing batch statistics is deployed to detect anomalies. In this setup, finding the worst-case estimation performance degradation during a d...

摘要：We propose a distributed control, in which many identical control agents are deployed for controlling a linear time-invariant plant that has multiple input-output channels. Each control agent can join or leave the control loop during the operation of stabilization without particular initialization over the whole networked agents. Once new control agents join the loop, they self-organize their control dynamics, which does not interfere the control by other active agents, which is achieved by lo...
