<p>A method and apparatus for compensating for hysteresis in a system (150), the method comprising: determining a required input to the system (150) from an output of the system (150) using the Preisach model with the input of the Preisach model corresponding to the output of the system (150), and with the output of the Preisach model corresponding to the input of the system (150). The system (150) may be an adaptive optics system. The input x may be an input voltage of an actuator (102) that deforms a mirror (104), and the output y may be a value of a displacement of a mirror (104).</p> |
