This paper presents a Teacher Learning Based Optimization (TLBO) approach to tune the backstepping controller for effective control of a single-link flexible-joint manipulator. To assess the relative performance of TLBO, comparative studies have been carried out with the two other popular optimization techniques namely genetic algorithm and cuckoo search algorithm. The integral absolute error was...
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...
In present paper, a non-cascading converter is presented. It is very useful as far as overall efficiency of the converter is concerned. Here the input power is transferred to the load through a non-cascading scheme employed on the secondary side of an isolation transformer. It requires the intermediate capacitor of lower ratings and at the same time improves the power transfer capability of the converter...
This paper presents an application of self-tuning Fuzzy PI controller (STFPIC) in velocity form (VF) and position form (PF) to control the jacketed Continuous Stirred Tank Reactor (CSTR) in a cascade configuration. CSTR is a highly non-linear process and requires non-conventional intelligent control techniques for stable and efficient operations. Self-tuning fuzzy logic controllers are one such option,...
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)...
The aim of this work is to design a speed controller of a DC motor by selection of PID parameters using bio-inspired optimization technique of Artificial Bee Colony Optimization (ABC). Here, model of a DC motor is considered as a second order system for speed control. In this work bio-inspired optimization technique in controllers and their advantages over conventional methods is discussed using MATLAB/Simulink...
A mathematical model has been developed that could predict kinetic parameters for the adsorption of divalent cations (lead, copper and zinc) onto low-grade rock phosphate using experimental data. The experiments were conducted with the initial concentrations of metal ions ranging from 10 to 100 mg/L. The mathematical model is based on application of Freundlich isotherm to mass transfer across the...
