According to biological strategy for pest control, we investigate the dynamic behavior of a pest management SEI model with nonlinear incidence concerning impulsive strategyperiodic releasing infected pests at fixed times. We prove that all solutions of the system are uniformly ultimately bounded and there exists a globally asymptotically attractive pest-eradication periodic solution when the im...

In this paper, a novel adaptive attitude tracking control method is investigated to enhance performance and robustness for quadrotor unmanned aerial vehicle (UAV) against the modeling uncertainties external disturbances. First, dynamics of UAV based on modified Rodrigues parameter (MRP) derived. Then, an dynamic surface technique with robust integral sign error (RISE) approach are designed impr...

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...

This paper presents the design of a variable structure-like tracking controller for a mobile robot system. The controller provides robustness with regard to bounded disturbances in the kinematic model. Through the use of a dynamic oscillator and a Lyapunov-based stability analysis, we demonstrate that the position and orientation tracking errors exponentially converge to a neighborhood about ze...

A networked control system is characterized by having a feedback loop closed through a local area network. This paper considers methods for scheduling the use of the network to guarantee both stability and controller performance. We propose and validate algorithms for choosing message identiÞers for dynamically scheduled networked control systems. Two schemes for selecting priority levels are p...
