Determination of a time-dependent potential in the higher-order pseudo-hyperbolic problem

在高阶伪双曲问题中确定时变位势

作者：M. J. Huntul

摘要：

The scope of this paper is to determine the time-dependent potential term numerically in the fourth-order pseudo-hyperbolic equation with initial and boundary conditions from an additional measurement condition. From the literature, we already know that this inverse problem has a unique solution. However, the problem is still ill-posed by being unstable to noise in the input data. For the numerical realization, we apply the Crank–Nicolson finite difference method combined with the Tikhonov regularization to find a stable and accurate numerical solution. The resulting nonlinear minimization problem is solved computationally using the MATLAB routine lsqnonlin. Both exact and numerically simulated noisy input data are inverted. Numerical results presented for two examples show the efficiency of the computational method and the accuracy and stability of the numerical solution even in the presence of noise in the input data.

The exact (Equation21) and numerical solutions for u(x,t), with various grid sizes M = N for: (a) 10, (b) 20 and (c) 40, for direct problem. The absolute error between them is also included.

Disturbance observer-based fuzzy adaptive optimal finite-time control for nonlinear systems

基于扰动观测器的非线性系统模糊自适应最优有限时间控制

作者：Zidong Sun et al.

摘要：

This paper investigates the issue of disturbance observer-based fuzzy adaptive optimal finite-time control in light of the backstepping approach for strict-feedback nonlinear systems with bias fault term and full state constraints. Considering that external disturbance and bias fault signal can affect the stability of control and control quality, a disturbance observer is constructed to track the external disturbances and bias fault online. A disturbance observer-based finite-time control strategy is proposed to achieve optimized control by utilizing the fuzzy logic system approximation-based adaptive dynamic programming method under the critic-actor framework. The purpose of the critic is to evaluate control performance and the role of the actor is to execute control behaviour. In addition, it is proved that the proposed fuzzy adaptive optimal finite-time scheme not only realizes all signals in closed-loop system are bounded, but also ensures that system states are restricted within specific sets. Finally, simulation results are shown to demonstrate the effectiveness of the proposed control strategy.

Optimal control analysis of coffee berry borer infestation in the presence of farmer's awareness

农民意识下咖啡果螟虫害的优化控制分析

作者：Mohammedsultan Abaraya Abawari et al.

摘要：

Coffee is the most critical stimulant beverage in the world and represents a significant source of income in many tropical and subtropical countries. In this paper, a deterministic mathematical model has been formulated to describe the infestation dynamic of coffee berry borer (CBB) using a system of non-linear ordinary differential equations with farmers' awareness and optimal control. The system has two equilibrium points, namely the CBB free equilibrium point and the endemic equilibrium point which exist conditionally. The basic reproduction number, which plays a vital role in mathematical epidemiology, was derived. The qualitative analysis of the model revealed the scenario for both CBB free equilibrium and endemic equilibrium points. The local stability of the equilibria is established via the Jacobian matrix and Routh–Hurwitz criteria, while the global stability of the equilibria is proven by using an appropriate Lyapunov function. The normalized sensitivity analysis has also been performed to observe the impact of different parameters on the basic reproduction number. We extended the proposed model into an optimal control problem by incorporating two control variables, the effort made to reduce the colonizing females based on chemicals, traps, and biological control using entomopathogenic fungi such as Beauveria bassiana, that are applied to the surface of the coffee berries and kill the colonizing females of CBB when they drill an entry hole into the coffee berry and the effort made to increase the awareness of farmers through media campaign and education for the coffee farmer. Then the optimal control strategy is found by minimizing the number of CBB individuals considering the cost of implementation. The existence of optimal controls is examined using Pontryagin's minimum principle. Finally, the numerical simulations show agreement with the analytical results.

Impact of aware farmer growth rate and awareness rate on the CBB population.
