サンプル値Ｈ∞制御に基づく超音波モータの速度追従制御 Speed Tracking Control of Ultrasonic Motors via Sampled-Data H.INF. Control
In this paper we consider a synthesis problem of digital controller for speed tracking control systems of ultrasonic motors. In the previous work, continuous-time <I>H</I><SUB>∞</SUB> control based synthesis involving Tustin transformation has been utilized to solve the problem, where it has been empirically known that over-estimation of modeling error is needed to avoid speed fluctuation in high frequency range. In this paper, it is shown that desirable performance can be obtained by sampled-data <I>H</I><SUB>∞</SUB> control synthesis without such conservativeness in modelings.
