Piezoelectric stack actuators (PESAs) are widely used in applications requiring a fast response, high resolution, and accuracy. The self-heating of PESA during continuous drive with large amplitude at frequencies can change its voltage displacement charge characteristics. These changes lead to loss stability inaccurate positioning systems. In this paper, we confirmed that by using our proposed ...
