Design of digital controller using pole placement method

Pole placement approach of controller design is capable of providing system stability, setpoint tracking and disturbance rejection. The proposed work focuses on design of a digital controller using pole placement method for magnetic suspension ball system which is an open loop unstable system. The digital controller design is a 2-DOF controller using the transfer function approach for given constraints in terms of peak overshoot and rise time. The objective is to determine a controller which satisfies the specialized constraints. This paper introduces design process for a digital controller using pole placement method for a magnetic suspension system.
