Design of controllers with arbitrary convergence time
TL;DR: The sufficient condition for Lyapunov stability is also given for this arbitrary chosen time stable system and the efficacy of the proposed method is illustrated through a practical system, viz., magnetic suspension system.
Proceedings ArticleDOI
Particle swarm optimization algorithm and its parameters: A review
TL;DR: This paper gives a detailed description of the PSO algorithm and significance of the various parameters involved in its update rule and highlights the advantages and disadvantages of usingPSO algorithm in any optimization problem.
Journal ArticleDOI
Optimization of Fractional Order PID Controller Using Grey Wolf Optimizer
TL;DR: In this paper, the grey wolf optimizer is used to tune both integer and fractional order controllers for controlling two classes of systems: time-delay and higher-order system.
Journal ArticleDOI
Optimized PID Controller for Magnetic Levitation System
TL;DR: The effectiveness of the proposed controller is validated by comparing it with the classical tuning criterion and the system performance is improved in terms of time & frequency domain by optimizing the parameters of the PID controller using grey wolf optimizer (GWO).
Journal ArticleDOI
Color Directional Local Quinary Patterns for Content Based Indexing and Retrieval
TL;DR: The retrieval performances of the proposed descriptor show a significant improvement as compared with standard local binary pattern LBP, center-symmetric localbinary pattern (CS-LBP), Directional binary pattern (DBC) and other existing transform domain techniques in IR system.
