Abstract :
The design of discrete-time H2 optimal controllers in the presence of constraints in the plant input is presented. The method is applied to the model of an experimental flex-arm, which has some nonminimum-phase zeros and all its poles on the unit circle. Experimental and simulation results on the performance of a fifth-order controller thus obtained are presented. The results suggest that this method of controller design ensures good performance of the closed-loop system
