The repetitious nature of that form of driving compared to a country road would differentiate a theta state and a beta state in order to perform the driving task safely 为了安全完成驾驶任务，在高速公路上驾车与在乡村公路上驾驶车辆的状态相比，可区分出波与波状态。

The experimental results show that piezoelectric self - sensing actuator can effectively measure its displacement signal under the conditions of different wave forms of driving voltage and different driving voltage frequencies 实验结果表明，在不同的驱动电压波形、不同的驱动电压频率下，基于积分器的压电陶瓷自感知执行器均能够很好地获取执行器的位移信号。
