| Abstract: | A novel design of self-adjusting PI controller was designed to solve the problem that the parameters of the traditional controller in scanning probe microscopy(SPM) are difficult to be adjusted.The hardware construction and software design were described.The PI controller based on DSP is realized by implementing the scanning parameter optimization algorithm.The experimental results show that the controller can automatically measure,calculate and optimize the PI parameters.The quality of SPM scanning images ... |
