The present publication is directed to utilize particle swarm optimization (PSO) algorithm based PI controller for adjusting the speed of brushless DC motor fed via four switch three phase inverter. The inverter topology reduces the cost and complexity of the drive system. High performance response during transient and steady state conditions is achieved by optimizing the controller gains using POS algorithm. The obtained results confirm the validity of the proposed drive configuration in providing the features of fast dynamic response (the settling time is about 0.025 s), with minimized percentage overshot, and approximately zero steady state error. Moreover, the drive system shows robustness feature when subjected to external load torque disturbances.
This paper presents an attractive approach for teaching the self-excited induction generator. Three operating conditions of the generator are mathematically modeled and then simulated using conventional Matlab commands. Active windows with these models are created using Matlab's Graphical User Interface capability. An example is given to demonstrate the usefulness of the developed tool.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
