Claim Text:
1. A controller for actuating a micromechanical actuator in a closed loop circuit, comprising: a first signal input to receive a reference signal; a second signal input to receive a measuring signal which denotes a recorded response by the micromechanical actuator to a control signal; a first controller element to at least one of filter and attenuate at least one of predefined frequency modes and predefined frequency components in a received reference signal and to output at least one of a filtered and attenuated reference signal; a second controller element to modify a received measuring signal to minimize a quality of at least one of a first mode and further modes of the closed loop circuit and to output a modified measuring signal; a third controller element to minimize a deviation between the at least one of the filtered and attenuated reference signal and the received measuring signal and to output a minimized reference signal; and a fourth controller element to adapt the received measuring signal to adapt a bandwidth of the closed loop circuit and to add the adapted measuring signal to a sum of the minimized reference signal and a modified measuring signal, which creates a control signal.
