AbstractTracking of the position of a moving object is an important engineering problem in manyareas including military industrial medical and consumer applications This problem hasbeen effectively solved with an Inertial Measurement Unit IMU that consists of threeorthogonally placed accelerometers and gyroscopes The resulting structure measures thelinear acceleration and angular velocity of the mounting object in three dimensions Knowing these parameters is enough to track the motion of the system with the help ofadditional mathematical operations Micro Electro Mechanical Systems based vibratory rate gyroscopes are preferred inmost emerging applications due to major reduction in fabrication cost size and powerconsumption as well as ease of integration with digital and electronic control systemscompared to precise ring laser and fiber optic gyroscopes These applications includerobots navigation GPS based navigation systems backup smart airbags anti lock brakingsystems video camera picture stabilization virtual reality headsets Although these sensorsinitially fit for applications where cost and size are more important than performance currently their performances satisfy and even surpass conventional sensing systems In this dissertation fundamentals of operation of the micromachined vibratory rategyroscopes have explained with emphasis on dynamical relations oscillation patterns characteristics of gyroscope response to rotation rate induced coriolis force and phaserelations A gyroscope has been analyzed emphasizing on a suspension system analysis b analysis of damping mechanisms with the aim of optimizing structure design and c electrical analysis including electrostatic drive and capacitive detection methods Resultsfrom this analysis show the desired operation of micromechanical system
