Abstract :
A case study in robust control is presented which assesses the availability of two robust stabilization methods for practical purposes. The methods considered accomplish H∞ robust stabilization and quadratic stabilization, respectively. The system of concern is a helicopter-like laboratory model with two degrees of freedom. A comparison of the systems shows the superiority of the quadratically stabilizing controller. The main reason for this lies in the fact that uncertainty structure is considered in the Lyapunov-based design
