摘要：For a class of uncertain, multiple-input-multiple-output nonlinear systems, we consider the problem of prescribed performance tracking control under strict control input constraints. By prescribed performance, we mean that outputs of the system should track the given reference signals, with tracking errors confined within a user-specified performance envelope. However, as the controller imposing this desirable behavior is subject to inelastic control input constraints, the reference signals ar...

摘要：In this article, the output regulation for a 1-D wave equation where the disturbances generated from an unknown finite-dimensional exosystem appear in all possible channels is studied. The system is first transformed into a new system for which the disturbance appears in tracking error only. An adaptive observer approach is adopted in investigation to estimate all possible unknown frequencies that have entered into a transformed new system. By the estimates of the unknown frequencies, we are a...

摘要：This article aims to solve the global practical prescribed-time stabilization problem of a class of nonlinear systems by bounded static and dynamic event-triggered control (ETC) and self-triggered control (STC) algorithms with a tradeoff performance. First, a static event-triggered mechanism is designed to update the control law based on the parametric Lyapunov equation containing a time-varying parameter that will approach to infinity at the prescribed settling time. This method can achieve t...

摘要：We propose a method for designing 2-D limit-cycle oscillators with prescribed periodic trajectories and phase response properties based on the phase reduction theory, which gives a concise description of weakly perturbed limit-cycle oscillators and is widely used in the analysis of synchronization dynamics. We develop an algorithm for designing the vector field with a stable limit cycle that possesses a given shape and also a given phase sensitivity function. The vector field of the limit-cycl...

摘要：For networked control systems, cyber-security issues have gained much attention in recent years. In this article, we consider the so-called zero dynamics attacks, which form an important class of false data injection attacks, with a special focus on the effects of quantization in a sampled-data control setting. When the attack signals must be quantized, some error will be necessarily introduced, potentially increasing the chance of detection through the output of the system. In this article, w...

摘要：This article is concerned with the saturated feedback stabilization for a nonuniform Timoshenko beam with boundary control matched unknown internal uncertainties and external disturbances. An infinite-dimensional disturbance estimator without involving high gain is designed to estimate the total disturbances. By compensating/canceling the total disturbances in the feedback loop and combining with a collocated stabilizing controller without uncertainty, we propose an unsaturated feedback contro...
