Design of Digital Pole placement Controller for a Ball & Beam system
Journal Title: GRD Journal for Engineering - Year 2016, Vol 1, Issue 0
Abstract
The Ball and Beam system is a nonlinear unstable system due to this property it is used as a bench mark problem for many researchers. The proposed work focuses on the design of a digital pole placement controller for a Ball and Beam system (BBS) connected with servo motor which is an open loop unstable system due to the presence of multiple poles at the origin. A one degree of freedom (DOF) and 2-DOF digital pole placement controller is designed using the discrete transfer function for the specified constraints namely peak overshoot and rise time. The digital controller designed is capable of providing system stability and also provides good set point tracking and disturbance rejection. The simulation result shows the feasibility of using the proposed controller for control of an unstable Ball and Beam system.
