Optimal preliminary design of electromechanical actuators

Estimation models for the preliminary design of electromechanical actuators

This paper presents estimation models for the model-based preliminary design of electro-mechanical actuators. Models are developed to generate all the parameters required by a multi-objective design, from a limited number of input parameters. This is achieved by using scaling laws in order to take advantage of their capability to reflect the physical constraints driving the actuator's component...

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...

Dynamic Electromechanical Coupling of Piezoelectric Bending Actuators

Abstract: Electromechanical coupling defines the ratio of electrical and mechanical energy exchanged during a flexure cycle of a piezoelectric actuator. This paper presents an analysis of the dynamic electromechanical coupling factor (dynamic EMCF) for cantilever based piezoelectric actuators and provides for the first time explicit expressions for calculation of dynamic EMCF based on arrangeme...

Carbide - derived carbon - based electromechanical actuators

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...
