System Modeling, Simulation, and Analysis of Electrohydrostatic Actuator for Armoured Recovery Vehicles

The electrohydrostatic actuator (EHA) is an emerging technology which is being used extensively and effectively in the field of aviation to control the aircraft which otherwise was the difficult task. It is a modular and compact design obtained by combining various cutting edge technologies. This technology has replaced the bulky and leak prone centralized hydraulic system with a compact and modular design. Fixed pump variable motor simulation (FPVM) model is developed to analyze the digital prototype of physical model to predict its performance in real world by using the software tool advanced modeling environment for performing simulations of engineering systems (AMEsim). The performance of the simulation model is tested with and without load. The open- and the closed-loop system analysis are carried out. The thermal analysis is also done using proportional integral derivative (PID) controller.
