According to biological strategy for pest control, a mathematical model with periodic releasing virus particles for insect viruses attacking pests is considered. By using Floquet’s theorem, small-amplitude perturbation skills and comparison theorem, we prove that all solutions of the system are uniformly ultimately bounded and there exists a globally asymptotically stable pesteradication period...

In this paper, an event-triggered adaptive dynamic programming (ADP) method is proposed to deal with the H∞ problem unknown and constrained input. Firstly, H∞-constrained regarded as two-player zero-sum game nonquadratic value function. Secondly, we develop Hamilton–Jacobi–Isaacs(HJI) equation, ADP solve HJI which equivalent solving Nash saddle point of game. An event-based single-critic neural...

In this article, we propose a new observer design for systems whose output is sampled in an aperiodic and asynchronous way which continuous-time homogeneous of negative degree available. The proposed method consists adapting the existing order to cope with fact that only measurements are available instead continuous ones. obtained error shown be globally uniformly ultimately bounded any upper b...

In practice, the unbalanced mass of propeller is leading cause vibration in a quadcopter. Therefore, this paper proposes an additive-state-decomposition notch dynamic inversion controller to suppress noise. Firstly, mechanics model based on established and its characteristic frequency analyzed. Then, specific form filter designed, taken as internal parameter. Next, stability analysis shows that...
