Validation tests have been achieved with tested structures represented by
different masses. These tests show that the control strategy permits to guarantee
good dynamic performance in spite of uncertainties (Figure 5).

1.4 - Conclusion
Robust control permits to take into account the uncertainty of the test
bench. Thus tests can be achieved under better conditions and with good
performance. The complexity of the control system is not much higher than with a
classical PID and so robust control is benefic.
