This article explores a novel fuzzy logic controller (FLC) based threephase shunt active power line conditioners (APLC) for power quality improvements due to the non-linear loads. The fuzzy logic controller is Mamdani-type and linguistic description, so it does not necessitate a mathematical model of the system. The FLC controller is capable of controlling harmonic current and dc-side capacitor...

In this paper, a hybrid particle swarm optimization genetic algorithm LQR controller is used on quarter car model with an active suspension system. The proposed control utilized to overcome the shortcoming that weight matrix Q and R determined by experience in traditional method. method makes it possible achieve optimal effect. A full-order state observer observe of suspension. road input are p...
