is considered. T he control design specifications of the benchmark is firstly
recast intoamixed HI/l1 optimisation problem, which is solved viaaconvex
optimisation approach. A globally optimal Pareto curve is produced via the
optimisation. It presents the limits of performance and is served asareference
for restricted complexity controller design. Then, controllers with different
complexity are designed viaadirect optimisation approach. The performance
indices of these controllers are compared with the global Pareto curve. Based on
the comparison, the controller with three parameters is determined as the one
achieving acceptable performance with lowest complexity. Experimental results on
the real system confirm the satisfactory performance achieved by the controller.
