Abstract: The study highlights three different control techniques namely proportional integral derivative (PID), adaptive neuro fuzzy inference system (ANFIS) and neural networks (NNs) for the control of highly nonlinear triple inverted pendulum system mounted on a carriage. The objective is to control the complete system within 3.0 sec using above mentioned controllers. The controllers were compared in terms of performance attributes like settling time, steady state error and overshoot responses. The results indicate better performance of ANFIS controller compared to PID and NN controllers. The study also highlights the effect of shape, number and type of membership function on training of ANFIS controller. The study further proposes an ANFIS controller which has been designed using only three membership functions and can successfully solve the problem of rule explosion associated with fuzzy controllers.
