Abstract This paper presents nature-inspired optimization algorithms such as particle swarm optimization (PSO) algorithm and bat algorithm (BA) for tuning PID controller parameters of BLDC motor drive. Both PSO algorithm BA are population based algorithms. Population based algorithms have number of advantages over classical methods for solving complex optimization problems. The position of BLDC rotor […]
Abstract This paper presents a new design concept for cascade control of brushless direct current (BLDC) motor drive. Cascade controllers are designed for definite separation of loops. This separation allows independent design of controllers with minimum interaction among loops. The resultant structure with inner loop and outer loop is a robust structure. Magnitude Optimum Multiple […]
Abstract The most widely used pulse width modulation scheme for diode clamped multilevel inverters (DCMLI) is the multicarrier based sinusoidal pulse width modulation. Though this technique is simpler and more flexible for implementation, the maximum peak of the fundamental component in the output voltage is limited to fifty percent of the voltage in the DC […]
Abstract Microgrid at islanding mode is operated with renewable energy sources like Solar, Wind and non-renewable energy sources like Diesel generator and Battery which supply load to the system efficiently. With the change in load there is frequency deviation and controllers are required. There is a requirement to tune controllers to have optimal utilization of […]
Abstract This paper deals with the design of a miniature servo controller for a short duty flow control actuator. The servo controller is designed for position control of the flow control actuator (FCA) with high accuracy. The flow control actuator in this application demands quick response, fine precision and compact size. The controller is required […]
Abstract Cell segmentation and counting has a very important role in diagnosing diseases and in the treatment process. But the complexity of the histopathological images and the differences in cell groups make this process very difficult, even for an expert. In order to facilitate this process, analysis of histopathological images is performed by using computer […]
Abstract As the day-by-day the depletion of the existing conventional electrical energy resources and the incorporation of technological developments in various sectors increasing the gap between the generation and demand. These situations demands to think of the renewable energy resources or the combinations of different energy sources as hybrid energy system. This is one of […]
Person can certainly prefer to enjoy only one reached plus 2x the degree of his/her bet. This method are different with just how it really is offered. A number of furniture let a fabulous Dual with just about any two playing cards and some take only if the amalgamation of the a pair business cards […]
