Abstract
A non-minimum phase multivariable system is controlled by three techniques to compare performance and robustness: decoupling/PID, LQG/LTR and $H_{\infty}$. The presence of a real half plane (RHP) zero entails challenges to design a robust control which frequency-based techniques (LQG/LTR and $H_{\infty}$) are better suited to deal with. However, decoupling the non-minimum phase multivariable system properly yields a robust performance as well.
