FUZZY LOGIC BASED WIDE-RANGE VIBRATION CONTROL SYSTEM

Abstract

A PC based generalised vibration control system has been developed using fuzzy logic. The -hardware . system, on which the controller software has been designed is a vibration table meant primarily for testing energy-meters of various types. Generalisation of the controller aims at making it, free `to the maximum possible extent, from the dependencies on the behaviour of the hardware and on load variations. This is attempted by providing neat interfaces for conveniently. changing the controller -characteristics as and when required. The structure" of the controller is based on fuzzy , patterns , hence the " changes to be made during improvisations have a better prospect . ' of meeting the intuitions. The control was implemented in real-time on the aforementioned vibration test-system, and its performance tested. The control system has been proved in regards to its controlling capability, thereby validating the fuzzy logic controller. The control system software has been developed in Turbo C++. The operating system was MS-DOS 6,22.
