Electrostatic chuck voltage filtering method, controller, and electrostatic chuck system
ActiveCN121643698Bcontrol workwork reliablyDigital technique networkKaiman filterControl engineering
This application discloses an electrostatic chuck voltage filtering method, controller, and electrostatic chuck system. The method includes: acquiring voltage sampling data of the electrostatic chuck; determining the target operating condition type of the electrostatic chuck based on the voltage sampling data; adjusting a preset Kalman filter based on the target operating condition type to obtain an adjusted Kalman filter; and filtering the voltage sampling data based on the adjusted Kalman filter. This application can identify the target operating condition type of the electrostatic chuck and adaptively adjust the filtering parameters of the Kalman filter based on the target operating condition type, so that the driving voltage output by the Kalman filter quickly approaches or matches the actual driving voltage, thereby controlling the operation of the electrostatic chuck in a timely, fast, and high-precision manner, ensuring that the electrostatic chuck can operate reliably, stably, and with high precision.
