The main aim of this paper is to design a hybrid force-position controller using fuzzy logic (FL) for the robotic arm of a 9 degrees of freedom (DOF) upper limb wearable exoskeleton rehabilitation robot. The robot is designed and built in our lab for assisting in the rehabilitation of patients post-stroke. The robotic arm of the rehabilitation robot is driven by pneumatic muscles (PM) and its dynamic...
Direct torque control based on space vector modulation (SVM-DTC) preserve DTC transient merits, furthermore, produce better quality steady-state performance in a wide speed range. In this paper, a torque fuzzy logic controller was designed to substitute the original torque PI controller, and a fuzzy SVM-DTC system based on the torque fuzzy controller was given. A new integration algorithm for estimating...
This paper investigates a fuzzy logic (FL) based current controller for a high voltage direct current (HVDC) plant connected to a weak AC system under the EMTP RV simulation environment. A typical HVDC system is modeled with a detailed representation of the converter, converter controls and AC system. An incremental fuzzy gain scheduling proportional and integral controller (IFGSPIC) is used for the...
