In this paper, we present a parallel implementation of the Particle Swarm Optimization (PSO) on GPU using CUDA. By fully utilizing the processing power of graphic processors, our implementation provides a speedup of 215x compared to a sequential implementation on CPU. This speedup is significantly superior to what has been reported in recent papers and is(More)
Multilevel inverters form a popular class of high-power inverters due to their high-voltage operation, high efficiency, low switching losses, and low electromagnetic interference. Metaheuristics, such as the genetic algorithm (GA), have been used with success to compute optimal switching angles for multilevel inverters with many dc sources while minimizing(More)
An unprecedented surge of developments in mobile robot outdoor navigation was witnessed after the US government removed selective availability of the global positioning system (GPS). However, in certain situations GPS becomes unreliable or unavailable due to obstructions such as buildings and trees. During GPS outages, a positioning solution with a minimum(More)
This paper presents a method of detecting rotor faults in induction motors using the fast orthogonal search (FOS). Proper online condition monitoring of induction machines is very important to ensure safe operation, timely maintenance, and efficiency. It has been shown that when a fault occurs in the rotor, it will exhibit itself as a series of sidebands(More)
A robust adaptive nonlinear controller is designed for a Doubly-Fed Induction Generator (DFIG) wind turbine supplying a power grid. The controller main objective is to guarantee that the generator active and reactive power are kept constant despite grid voltage and frequency variations. A model based control design method is proposed. The controller(More)
Unlike commercial airlines that fly predetermined trajectories, military unmanned aerial vehicles (UAVs) operate in dynamic environments and must often adjust their itinerary based on the developing conditions during the mission. The path planner module is a key element of any autonomous UAV. It computes the optimal path from a start point to an end point.(More)
This paper presents a three-level three-phase diode clamped inverter that uses an auxiliary circuit to equalize its DC-bus capacitor voltages. The proposed converter is used in a Static Compensator (StatCom) and a controller is designed for this new StatCom. A state space model of this compensator connected to a grid is obtained first. Three single input(More)
This paper presents a new trend in the transportation industry to adopt the multilevel inverter-based propulsion systems and gives the design procedure of a new dc/ac 3-phase 7-level inverter for powering rail metro cars. The novelty of the proposed inverter lies within the proposed control methodology, which uses a new switching pattern that guarantees a(More)
The aim of this paper is to present a position based impedance control scheme using a Fuzzy Model Reference Learning Controller (FMRLC). In the proposed control scheme, the static relationship between displacement and force is quantified through a desired stiffness. The desired dynamic behaviour of the system is quantified through the use of a reference(More)
Power distribution networks are typically structured in a radial topology with extra tie switches to allow for a manual reconfiguration in case of unexpected failure or scheduled maintenance. With the implementation of the smart grid, it is now realistic to also consider the power demand fluctuation and have real-time reconfiguration of the network to(More)
