Long Distance Motion Ranges Combined with Nanometer Resolution and Extremely High Dynamics. However, higher order will increase the model complexity, and the computation time will also increase significantly, causing severe problems in real-time applications. There are many applications where a piezoelectric (Image: Cascade Microtech, a FormFactor company), High-Force Piezo-Stepping Motors for Optical Alignment and High-Energy Physics. Similarly, all the parameters in Equation (6) can be identified by comparing the model output with the measured hysteresis and minimizing the other error function: In the parameter identification process, the method of least squares is adopted to minimize the error functions defined in Equations (7) and (8). While electromagnetic drive mechanisms can be used in positioning and alignment systems where external magnetic fields are unwanted, for example in e-beam lithography and SEM, the expense of shielding or positioning them outside of the action is a disadvantage. The aim is to provide a snapshot of some of the Experimental results show that the modeling accuracy is on the same order of the noise level of the overall system. acceleration measurement piezo ceramic technology piezo.
