Design of Hysteretic Nonlinear Experimental Platform for Piezo-positioner Based on dSPACE

硬件名	硬件参数
压电陶瓷纳米定位器	输入电压范围为−20~100 V，输出位移最大为115 μm，内置高分辨率电容传感器
上位机	高性能计算机，并装有MATLAB 2018b及ControlDesk
dSPACE及转接板装置	DS2103中的MUX_DAC模块将Simulink 输入的±1转化成±10 V的电压输出信号，DS2002中的MUX_ADC模块将输入的 ±10 V的电压信号转换成±1的Simulink输出
电压放大器	输入电压范围为−2~120 V 输出电压范围为−30~130 V
信号监视器	将压电定位器产生的位移信号转换成 0~10 V电压信号
