The reason for this interest lies in the fact that all physical communication channels have limited bandwidth, which imposes restrictions on the transmission of data. The basic idea of our work is adopted from the definition of stability used for infinite dimensional systems. The main contribution is to give a new result for synchronization of infinite dimensional discrete-time chaotic system connected by bandlimited channels. Sufficient condition in terms of the added system parameters and the inserted filter coefficients will be stated. Once applied for data communications, the currently drawn up synchronization scheme pledges to enhance the transmission robustness. Indeed, the new considered parameters act like novel secret keys which widen the cipher key space. Simulation results using MATLAB software illustrate the effectiveness of our approach.

In the RKM method, components such as points, space, inner product, bases, and a suitable method have an effect on increasing the accuracy. The easy implementation, elimination of the Gram–Schmidt process, fewer calculations, and high accuracy of the present method are interesting. The compatibility of numerical results and theorems demonstrates that the Present method is effective.

Controlling quadcopters is a major concern, and researchers are actively studying it. In this study, altitude control of a quadcopter UAV is achieved using the symbolic limited optimal discrete controller synthesis technique. The resulting controller is compared with the adaptive PID control method, where the PID controller's parameters are determined using the Dragonfly algorithm. The findings show the superior performance of our approach. LA - English DB - MTMT ER - TY - JOUR AU - Pranupa, S. AU - Sriram, A. T. AU - Rao, S. Nagaraja TI - Wind farm layout optimization approach using bio-inspired meta-heuristic algorithm to minimize wake effect JF - INTERNATIONAL JOURNAL OF DYNAMICS AND CONTROL J2 - INT J DYN CONTROL PY - 2023 PG - 20 SN - 2195-268X DO - 10.1007/s40435-023-01172-y UR - https://m2.mtmt.hu/api/publication/34368992 ID - 34368992 AB - In this paper,wind farm layout optimization (WFLO) using bio-inspired meta-heuristic algorithm, i.e. artificial hummingbird optimization (AHO) algorithm, is proposed to optimise the wind farm's architecture in order to limit the wake effect on the wind turbines (WTs), hence lowering the per-unit cost of electricity generation. In the current scenario of WFLO, a boundary equals to 2 x 2 square kilometre area is considered with 10 x 10 square grids. The suggested AHO algorithm is used to address the number of WTs to be installed and the placement of each WT. Furthermore, the AHO algorithm approach is inspected in two separate wind cases (1) constant speed with variable wind direction (VWD), (2) variable speed with VWD. Additionally, the proposed AHO method is compared with the sparrow search optimization (SSO)-based bio-inspired meta-heuristic algorithm in terms of the various performance metrics which includes the efficiency of the farm, the power generated, number of WTs, and the convergence speed for two distinct situations of wind speed. The MATLAB results of WFLO using AHO and SSO approaches reveal that, for the same number of WTs, the AHO algorithm produced better output, efficiency and less cost/kW compared to the SSO algorithm.

This innovative mathematical model of diabetes is demonstrated and examined in fractional order by involving ABC fractional derivative. This whole framework is worked out using a semi-analytical technique, namely the Adomian decomposition Laplace transform method. To prove the efficiency of this ADLTM technique, the results are compared with other classical methods, viz. homotopy perturbation transform method and modified homotopy analysis transform method. Using the Banach fixed point theorem, the existence and stability analysis of the solution has been proved. Certain figures and tables are illustrated for this fractional diabetes model with some fractional order. We used the Maple software to generate all the numerics and graphical plots. This detailed investigation also explores how well the level of glucose and insulin affects the dynamics of disease infection.

The enhanced performance of cascade control depends on the effective tuning. However, after encountering the non-minimum phase zeros in the system, the tuning of cascade control becomes complex. This work proposes a modified Bode's ideal transfer function for tuning fractional filter. This modification is completed after consideration of non-minimum phase zeros in Bode's ideal transfer function approach. This modified tuning approach elucidated the common pitfalls in the existing techniques. Here, the internal model control (IMC) context is utilized to construct the outer loop controller of the series cascade scheme after embedding the fractional filter and inverse response compensator. Moreover, a rudimentary structure of the IMC scheme is revealed for the inner loop controller design. The suggested way enhances the non-minimum phase system performance without compromising setpoint tracking and disturbance rejection. Additionally, the Riemann sheet principle is utilized for the stability analysis. Sensitivity analysis is carried out to adjudge the robustness. The search space reduction algorithm is employed to optimize the closed-loop response utilizing an objective function that minimizes the integral of square error. Two case studies are utilized for effectuating the benefits of the suggested control approach associated with state-of-the-art.

In this article, we analyse the Maxey-Riley (M-R) equation that models the motion of a small particle in a non-uniform flow field. Fractional derivative arises naturally as a history term. We study the M-R equation in terms of fractional differential equations, a subject very well studied in recent times. This approach helps in gaining a deeper understanding of the underlying phenomenon. We observe solution curves having self-intersections, which is a novel feature of fractional-order dynamics.

For such a purpose, a partitionnement of the generalized coordinates explicit the output and the unobserved coordinates. In sequence, the equation of motion is algebraically modified resulting in a nonlinear differential equation, where states are the unobserved coordinates, and the input represent the second time-derivative of the output related to the original system. A dynamic programming and a collocation method are used to formulate the optimisation problems based on the optimal control theory. The internal dynamics is analyzed; the related optimal feedback control and feedforward control are designed using different methods. The algorithm will search for optimal trajectories of the internal dynamics that stabilizes the system in a constrained motion. The methodology is illustrated in simulation mode considering semi-passive, soft and flexible manipulators in 2D and a rotary inverted pendulum in 3D.

Optimal values of the controller constants are obtained using whale optimization algorithm. Different shapes of tracking path like circular, elliptical, infinity-shaped, etc., are considered to verify the tracking capability of the suggested method. Stability and robustness of the suggested control system are analyzed using Lyapunov stability criteria. Through various simulations, it is found that the proposed control strategy yields significantly improved tracking performance and enhanced robustness toward process parameter perturbations and load disturbances compared to conventional PID controller.
