A Micro-Electrical-Mechanical-Systems (MEMS) accelerometer system includes a proof-mass device having a proof-mass that moves from an initial position in response to an input acceleration, a transducer connected to the proof-mass device to output a transducer signal correlating to movement and/or position of the proof-mass, and a driver configured to drive the proof-mass. A controller actively controls the driver to actively drive the proof-mass toward an initial position, and actively adjusts the drive signal based on a temperature signal (T) indicative of given temperature, a transducer voltage signal (Vref) indicative of a transducer voltage reference, and the transducer signal to actively generate a corrected drive signal and delivers the corrected drive signal to the driver to actively control the driver. The controller can also utilize a robust loop-shaping stabilization operation to produce both an unfiltered estimate of the input acceleration and an uncorrected drive signal to stabilize the proof mass.
