This paper presents an effective design of a 2nd order infinite impulse response digital differentiator optimized using cuckoo search algorithm (CSA). In the proposed design scheme, sum of the coefficients of numerator terms was restricted to zero so as to approximate DC frequency response accurately. This restricted condition resulted in a much better approximation in terms of superior performance...
In this work, an application of constrained genetic algorithm (CGA) based optimization approach has been explored for design of low pass and high pass finite impulse response (FIR) digital filters. To accomplish the task of optimal filter design, a novel constraint function has been proposed and integrated with the fitness function in CGA environment. CGA minimizes the fitness function under supervision...
An optimization approach to design an efficient 2nd order infinite impulse response (IIR) digital integrator (DI) is proposed using Cuckoo search algorithm (CSA). The unique feature of the proposed approach has been the formulation of the condition for obtaining ideal DC frequency response which has been attained by forcing the sum of the z-term coefficients in the denominator equal to zero during...
This paper deals with a method of clipping a line segment into a circular window. Its unlike other algorithms, instead of dividing region into segments and generating the corresponding region codes, yields results based their parametric equations which not only yields precise result for each pixel but also compute faster. Its an algorithm that can be embedded in many circular displays in order to...
Metaheuristic or nature inspired optimization have evolved over time towards development of a general purpose optimizer. In this paper, a novel nature inspired algorithm, based on hunting mechanism of antlions, Ant Lion Optimizer toolkit is developed in LabVIEWTM environment. This paper provides an orderly procedure for development of toolkit including random walk of ants, building of traps, catching...
A comparative study of the performance of three optimization techniques, namely Cuckoo Search Algorithm (CSA), Flower Pollination Algorithm (FPA) and Genetic Algorithm (GA), is presented in this paper for tuning the gains of Self Organizing Fuzzy Controller (SOFC) applied to a two link planar rigid robotic manipulator. SOFC is an intelligent adaptive fuzzy logic control technique generally used to...
This article deals with the speed control of DC motor using a Fractional Order Proportional Integral (FOPI) controller. In this paper, the Particle Swarm Optimization algorithm (PSO) is implemented to optimally tune the controller gains of the FOPI controller for setpoint tracking and disturbance rejection where the optimization performance index is taken as Integral Time Weighted Absolute Error (ITAE)...
