(b) Assume that PID controller, K (s) K P K I / s K D s , is selected to compensate the requirement of system stability and zero steady state error to unit step input, use the Routh-Hurwitz test to show that a cascade of PID controller with the original plant and unity negative feedback configuration can meet the requirements. Remember that the system must be stabilized first before the consideration of steady state error.

ABSTRACT
Because of the nature of magnetic force, maglev is inherently non-linear and open loop unstable hence we need to design the linearized model in which most of the controllers are based on. The main parameters need to be satisfied by...

...INTRODUCTION
Control engineering is the discipline that applies controltheory to design systems with predictable behaviors. The practice uses sensors to measure the output performance of the device being controlled and those measurements can be used to give feedback to the input actuators that can make corrections toward desired performance. There are two major divisions in controltheory, namely, classical and modern,...
