The present invention relates to a control system for an electrostatically-driven microelectromechanical device, which uses multiple electrodes to control the microelectromechanical device, i.e. the lower driven electrode of a capacitor with known two parallel driven electrodes is cut into a number of small electrodes. By selecting an electrode pattern for a desired electrostatic force, it is capable of altering the non-linearity of the device based on various applications and achieving a characteristic such as a linear driven, digital driven, or ultimately optimal driven manners, which is able to reach high operation accuracy for the existing circuit that only possesses a limited accuracy.
