And the experimental tests had been carried out to verify the established model as well as the dynamic characteristics under opening loop control. 并通過(guò)實(shí)驗，對所建立的動(dòng)力學(xué)模型及開(kāi)環(huán)控制下平臺的實(shí)際動(dòng)態(tài)特性進(jìn)行了驗證。
A standing-wave-type stepping ultrasonic motor using the alternative operation of two bending vibration modes on the stator has no accumulative errors without the feedback. 摘要利用環(huán)形定子的兩個(gè)彎振模態(tài)交替工作的原理設計的一種駐波型步進(jìn)式超聲電機具有開(kāi)環(huán)控制下無(wú)累積誤差的特性。
