Abstract :
In this paper we consider synthesis problems for speed control systems of ultrasonic motors. In the previous work, it is empirically known that in continuous-time H∞ control based synthesis, conservative evaluation of modeling error is needed to avoid speed fluctuation in high frequency range. It is shown that desirable control experiment results are directly obtained by sampled-data H∞ control synthesis without such conservativeness in modelings.
