TSets Intelligent Controller for Electromechanical Positioning Actuators

A cognitive intelligent approach to the control of an electromechanical positioning actuator using Tendentious Vague Sets (TSets) is presented. The electromechanical positioning actuator prototype discussed is essentially a position control system whose constitutive elements are a PC based control unit, a Direct Torque Control (DTC) inverter and an induction motor. A generalisation of the fuzzy...

Fault Tolerant Electromechanical Actuators for Aircraft

This thesis reviews the developments in commercial aviation resulting from More Electric Aircraft initiatives. The present level of electromechanical actuation is considered with discussion of the factors affecting more widespread use. Two rather different electromechanical actuators are presented for commercial aircraft; DEAWS electrical flap actuation and ELGEAR nose wheel steering. Both proj...

Multi-Sensor Architecture for Intelligent Electromechanical Actuators

A versatile, actuator-based open machine architecture is needed to meet the increasing performance demands of modern mechanical systems. Actuators in such systems must have a complete knowledge of operating characteristics, with the ability to reconfigure resources to adapt to different conditions or user-choices.This generality of response is termed as intelligence. To achieve this objective, ...

Electromechanical Modelling of Ionic Electroactive Polymer Actuators

Migration of ions under electric field is the phenomenon behind the mechanical deformation of ionic polymer actuators. This transport process is influenced by numerous factors depending on the physical, chemical and electrical properties of the material used [1]. Among them porosity and tortuosity are one of the main influencing factors that modifies ion channels and so the properties of the ma...
