摘要:
A multisensor of the type that employs counteroscillating rotor-mounted accelerometers to measure both linear and Coriolis accelerations operates open loop to sense linear acceleration and closed loop to sense the Coriolis acceleration from angular rate inputs. Accelerometers mounted to arms of the counteroscillating rotors are designed so that the natural frequency of the proofmass with respect to the accelerometer frame closely approximates the resonant frequency .omega..sub.D of the driven rotor pair. A robust hinge design permits open loop operation for low frequency linear acceleration inputs without saturation. Low voltage closed-loop operation is made possible by the highly compliant nature of the resonant structure in responding to the much higher frequency Coriolis accelerations generated by angular rate inputs.
