摘要:Structural identifiability concerns the question of which unknown parameters of a model can be recovered from (perfect) input-output (IO) data. If all of the parameters of a model can be recovered from data, then the model is said to be identifiable. However, in many models, there are parameters that can take on an infinite number of values but yield the same input-output data. In this case, those parameters and the model are called unidentifiable. The question is then what to do with an unide...

摘要:The problem of trajectory tracking of autonomous aerial vehicles (AAVs) is researched by the aid of Rodrigues parameter (RP). With the attitude planner being designed, the underactuated translational system is transformed to the full-actuated form, and rotational error dynamics based-on RP is obtained. To avoid unwinding phenomenon, a continuous nested saturation controller is constructed such that the input-to-state stability of the closed-loop error system is obtained, which is equivalent to...

摘要:Although pinning control of dynamical networks with or without delay has been well explored in the past two decades, little attention has been paid to the delay originated from pinning control itself. This article investigates the delayed pinning control scheme for lag synchronization and lag quasi-synchronization of dynamical networks. Two pinning control schemes with uniform delay and nonuniform delays are proposed, which are more practical than the widely used delay-free pinning control sch...

摘要:This article aims at collaborative optimization of sum of convex functions over networks subject to globally coupled affine equality and inequality constraints whose partial information is known by each agent. The proposed discrete-time fully parallel distributed algorithm is the first of its kind in the sense that it does not require diminishing step size, (sub)gradient, and/or solving a subproblem at each time step. The algorithm is able to converge to an optimal solution for any local conve...

摘要:In this work, we develop a scheme for constructing continuous approximations (referred to as abstractions) of a class of discrete-time control systems with partially unknown dynamics. The abstraction, itself a nonlinear discrete-time control system (preferably with a significantly lower dimension than the original one) can be used as a substitute in the controller design process. The technique consists of using data sampled from the concrete system to find a lower dimensional subspace of its s...

摘要:We present a general framework for solving the problem of Nash equilibrium (NE) seeking with LTI agents subject to constant external disturbances. The framework consists of breaking down the design using a four-part control methodology. Using this methodology, we show that the problem is reduced to the design of a set of decentralized stabilizing controllers. We present one potential controller design using tools from passivity theory. Finally, we show the applicability of the framework throug...

摘要:This article considers quantized feedback control of discrete-time linear systems involving quantizations and saturations of the system input and state. A new representation of saturation map is presented by equality with bounded uncertain diagonal matrix and reduces conservatism. Further, based on spherical polar coordinate quantizer, the quantization error is converted to sector-bound uncertainty. Thus, the considered system is modeled as uncertain system and the considered problems are conv...

摘要:Networked systems must often balance privacy in avoiding leaking sensitive information, with utility in communicating the information that is needed by components to operate correctly. We consider the problem of enforcing privacy and utility with both obfuscation (altering communications to mislead eavesdroppers) and control (restricting system behavior to avoid information leakage). We present a formulation of this problem that models components of the networked system as interconnected react...

摘要:This article focuses on the adaptive linear quadratic Gaussian control problem, where both the state matrix A and the control gain matrix B are unknown. We only assume that (A, B) is stabilizable and (A, Q(1/2)) is detectable, where Q is the weighting matrix of the state in the quadratic cost function. This significantly weakens the classic assumptions used in the literature. To design an optimal adaptive control, a weighted least squares algorithm is modified by using random regularization me...

摘要:We study the problem of stabilizing infinite-dimensional systems with input and output quantization. The closed-loop system we consider is subject to packet loss, whose average duration is assumed to be bounded. Given a bound on the initial state, we propose a design method for dynamic quantizers with zoom parameters. We show that the closed-loop state starting in a given region exponentially converges to zero if bounds on quantization errors and packet-loss intervals satisfy suitable conditio...
