Designing fuzzy logic controller for inverted pendulum

Abstract

In control system, if all the states of the system are measured, then by using state feedback control law we can control the system. As we know that value of feedback gain cannot be found easily, it requires trial and error method for suitable pole locations. In certain applications state variables cannot be measured because of cost considerations or lack of suitable transducers. In such cases, state variables that cannot be measured must be estimated from the ones that are measurable. A device, which estimates states, is known as 'observer' or 'state observer'. To design observer, person has to face mathematical complexities. Here without facing mathematical complexities control system can be controlled using Fuzzy Logic Approach. © 2005 by International Federation for Information Processing.
