Intelligent controllers for eddy current energy absorber of aircraft arrester barrier system

摘要

Aircraft Arrester Barrier Systems (AABS) are installed near the end of runways for the purpose of arresting combat aircraft due to over shooting of runway length during aborted take-off and emergency landings. Energy Absorbing System (EAS) is one of the important subsystems of AABS.The energy absorber consists of two velocity sensitive turbine type conventional rotary hydraulic energy absorbers. There is no control in conventional EAS on energy absorption during operation of an aircraft emergency arrestment. Also, if there is any problem with conventional EAS during operation, complete system fails. For different types of aircrafts different EAS needed. To overcome these problems, we suggest to use the combination of existing conventional EAS and eddy current absorbing (ECA) system. This proposed (ECA) system with existing conventional system will help in the stopping of any Aircraft (like light weight, heavy weight, etc). The proposed eddy current EAS prototype has been implemented and intelligent controllers for eddy current EAS has been designed. The intelligent control system is developed for controlling the rate of retardation (energy absorption) of eddy current energy absorbing system. In this paper different intelligent controllers like ANN controller, fuzzy logic controller and neuro fuzzy controllers for eddy current braking system are implemented.
