Symbolic controller with PID feedback for locally linearized system

Abstract

In this paper, we proposed a novel symbolic controller with PID (proportional integral derivative) feedback for locally linearized system. The state-space of this system is analyzed in Brunovsky coordinates, and then a practical control structure which combines symbolic controller and PID controller is presented. Series of Experiments on an inverted pendulum are conducted, and the results show the feasibility and efficiency of our proposed structure. © 2011 Springer-Verlag Berlin Heidelberg.
