Abstract
This paper investigates the discrete-time solution of time-varying quadratic programming (TVQP) problems with linear equality constraints in noisy environments. Starting from the Karush-Kuhn-Tucker conditions, a perturbation-suppressed zeroing neural dynamics model is established to describe the online evolution of the optimal solution. For sampled-data implementation, a seven-instant discretization scheme is developed, yielding the proposed SE-DT-TVQP algorithm. For comparison, Euler-type and Taylor-type discrete-time formulations are also considered. Numerical experiments consisting of a baseline case without noise under the fixed sampling interval g=0.01, a constant-noise case, and a linearly time-varying noise case show that the proposed algorithm consistently achieves lower steady-state residuals and stronger noise resilience than the benchmark methods. These results demonstrate that the proposed seveninstant sampled-data design provides an effective sampled-data approach for online TVQP computation under perturbations.
This paper investigates stochastic iterative learning control (SILC) for discrete-time linear time-varying systems subject to process and measurement noise. High-order learning can smooth input updates by reusing historical errors, but a fixed high-order structure may sacrifice transient tracking performance when obsol...

This paper focuses on the joint non-fragile state and fault estimation issue for a class of stochastic nonlinear systems under the dynamic event-triggered transmission scheme (DETS). To better conform to practical engineering scenarios, we consider an additive fault whose second-order difference is piecewise zero. A ze...

Guaranteeing a prescribed convergence-time bound for stochastic nonlinear systems remains challenging when actuator faults and unmodeled dynamics are present. This difficulty becomes more pronounced when both loss-of-effectiveness and bias faults occur, since they may significantly degrade the transient regulation perf...

Intermittent state measurements pose fundamental challenges to model predictive control of constrained nonlinear systems because prediction uncertainty grows during feedback outages and measurement-triggered resets disrupt nominal state propagation, potentially compromising closed-loop stability and recursive feasibili...

This paper addresses a robust tracking problem for linear discrete-time systems by proposing a reinforcement learning (RL) control method based on a diagonal-scaling strategy, offering a solution tailored to the demands of enhanced reliability. To overcome a common limitation in policy-iteration-based RL design, namely...
