Metaheuristic techniques are extensively utilized to solve many complex and real-world problems. These techniques do not provide an exact solution, but only an estimated result in feasible time. Recently, many researchers have utilized these techniques for solving the various artificial intelligence (AI) enabled applications. These techniques are generally used in two different ways to improve the AI applications. In first case, these techniques can help for evaluating the potential features from the pool of features of a given machine learning/ deep learning problem. It can improve the performance and computation speed of the given machine learning/ deep learning models. In second approach, metaheuristic techniques are widely accepted to resolve the hyper-parameters tuning issue with the most of machine learning and deep learning models. Even metaheuristic techniques are accepted as a hyper-parameters tuning tool for various kind of other techniques such as chaotic map, deep generative models, fuzzy logic, chaotic maps, etc. Therefore, the metaheuristic techniques have their own importance in various fields of computational sciences. However, most metaheuristic techniques suffer from the pre-mature convergence, stuck in local optima, poor convergence speed, etc. kind of issues.

  • Non-integer Order Control Scheme for Pressurized Water Reactor Core Power
  • Abstract Tracking load changes in a pressurized water reactor (PWR) with the help of an efficient core power control scheme in a nuclear power station is very important. The reason is that it is challenging to maintain a stable core power according to the reference value within an acceptable tolerance for the safety of PWR. To overcome the uncertainties, a non-integer-based fractional order control method is demonstrated to control the core power of PWR. The available dynamic model of the reactor core is used in this analysis. Core power is controlled using a modified state feedback approach with a non-integer integral… More

  • Extremal Coalitions for Influence Games Through Swarm Intelligence-Based Methods
  • Abstract An influence game is a simple game represented over an influence graph (i.e., a labeled, weighted graph) on which the influence spread phenomenon is exerted. Influence games allow applying different properties and parameters coming from cooperative game theory to the contexts of social network analysis, decision-systems, voting systems, and collective behavior. The exact calculation of several of these properties and parameters is computationally hard, even for a small number of players. Two examples of these parameters are the length and the width of a game. The length of a game is the size of its smaller winning coalition, while the… More

  • Position Control of Flexible Joint Carts Using Adaptive Generalized Dynamics Inversion
  • Abstract

    This paper presents the design and implementation of Adaptive Generalized Dynamic Inversion (AGDI) to track the position of a Linear Flexible Joint Cart (LFJC) system along with vibration suppression of the flexible joint. The proposed AGDI control law will be comprised of two control elements. The baseline (continuous) control law is based on principle of conventional GDI approach and is established by prescribing the constraint dynamics of controlled state variables that reflect the control objectives. The control law is realized by inverting the prescribed dynamics using dynamically scaled Moore-Penrose generalized inversion. To boost the robust attributes against system nonlinearities, parametric… More

  • Fractional Order Linear Active Disturbance Rejection Control for Linear Flexible Joint System
  • Abstract A linear flexible joint system using fractional order linear active disturbance rejection control is studied in this paper. With this control scheme, the performance against disturbances, uncertainties, and attenuation is enhanced. Linear active disturbance rejection control (LADRC) is mainly based on an extended state observer (ESO) technology. A fractional integral (FOI) action is combined with the LADRC technique which proposes a hybrid control scheme like FO-LADRC. Incorporating this FOI action improves the robustness of the standard LADRC. The set-point tracking of the proposed FO-LADRC scheme is designed by Bode's ideal transfer function (BITF) based robust closed-loop concept, an appropriate pole… More
